Hasn't anyone noticed that not a single US plane has been hijacked in the past 10 years? A quick look at Wikipedia shows 7 US planes hijacked in the 1970s, several in the 80s and 90s. Four planes were hijacked in 2001 (all on the same day....) - and then not a single US, European, Japanese plane has been hijacked.

Something is working.....

Homer Simpson: Not a bear in sight. The Bear Patrol must be working like a charm.

Lisa Simpson: That’s specious reasoning, Dad.

Homer: Thank you, dear.

Lisa: By your logic I could claim that this rock keeps tigers away.

Homer: Oh, how does it work?

Lisa: It doesn’t work.

Homer: Uh-huh.

Lisa: It’s just a stupid rock.

Homer: Uh-huh.

Lisa: But I don’t see any tigers around, do you?

Homer: Lisa, I want to buy your rock.

I do actually know the difference between causal and correlational relationships.... :D

I will stand by my hypothesis that something that the TSA is doing is working to make hijackings less likely to happen in the USA.....

Just because hijackings are down doesn't mean that TSA is actually working. Since 9/11 we've had a guy who got c4 into his shoe, another who lit his underwear on fire, and countless TSA tests have shown guns and other weapons make it through without much trouble.

Our attempts at security are at best as good as Lisa's rock, and at worst much worse because they not only slow down travellers, curtail individual dignity, and cost billions, but also breed distrust and adversarial stances from the public that is supposed to be served.

I understand the point you are trying to make (re: enhanced security measures] but technically those two incidents had nothing to do with the TSA since they both flew from non-USA airports - that is, the TSA didn't screen them at all.
...and countless TSA tests have shown guns and other weapons make it through without much trouble.
I guess that depends on how you define "not much trouble". We can't know the actual number, since we will never know many actually get through. But they are catching over half the weapons that their own agents try to smuggle through on test/training runs. So that counts as being "some trouble". How much "trouble" is enough? Read my post above about how much risk a "bad person" organization is willing to take on 50/50 odds. My late father made his career "gaming" situations, so I have a bit of a passing knowledge of it. I am certain that the TSA has "gamed" the odds, and the TSA believe that they have reached a reasonable balance between costing the public time, money, and indignities - and - ensuring a reasonable level of safety for the flying public. They may be wrong.... but I would bet money that, to the best of their ability, they believe they have reached a balance.

OK, then why are hijackings down? I have my working hypothesis. I cited some evidence to support it. If you don't agree, then it is up to you to state an alternative one that is supported by more than unsupported statements.

I am not saying the TSA (or in my case CATSA) is perfect or haven't mucked things up sometimes. I'm just saying that I believe that they have been mostly responsible for a dramatic drop in airline hijackings. I cited some statistics. Now it's your turn.....

ps there is no proof that it wasn't Lisa's rock. There are some very weird causal relationships in the world. Like shooting wolves causes the Aspen to die off in Wyoming. Or .... overfishing the Salmon in the Pacific changes the mix of trees along the rivers of the BC coast.....

While this is true, we can't allow that technicality to wipe the slate clean. Our security as a whole is deficient, even if the TSA on its own might not be responsible for these two particular failures. Our tax dollars are still going to the our mutual safety so we should expect more.

Well when a fanatic is willing to commit suicide because he believes that he'll be rewarded in heaven, 50/50 odds don't seem to be all that much of a deterrent. What's worse is that we've only achieved that with a lot of our personal dignity, time, and money. I don't think we can tolerate much more. We should be expecting more for the time, money, and humiliation we're putting ourselves (and our 6 year-old children) through.

If this is the TSA's best effort and what it believes is the best balance, I want a new TSA.

Your statistics don't unequivocally prove the efficacy of the TSA though. They only show that the TSA employs a cost-benefit method to determine what measures to take.

Since you believe in the efficacy of the TSA so much, the burden is yours to make a clear and convincing case, not mine. I can provide alternative hypotheses, but I am in no way saying that these are provable at the current moment in time. I'm only saying that they are rational objections to your theory.

My hypothesis is essentially the same as Lisa's: the protection is coming from our circumstances rather than our deliberative efforts.

Terrorism is a complex thing. My bet is that as we waged wars in multiple nations, it became more advantageous for fanatics to strike where our military forces were. Without having to gain entry into the country, get past airport security (no matter what odds were), or hijack a plane, terrorists were able to kill over 4,000 Americans in Iraq and nearly 1,500 in Afghanistan. That's almost twice as many as were killed on 9/11.

If I were the leader of a group intent on killing Americans and Westerners in general, I certainly would go down that route rather than hijack planes.

ps there is no proof that it wasn't Lisa's rock. There are some very weird causal relationships in the world. Like shooting wolves causes the Aspen to die off in Wyoming. Or .... overfishing the Salmon in the Pacific changes the mix of trees along the rivers of the BC coast.....

It's pretty clear that it was not the rock. Ecosystems are constantly finding new equilibriums; killing off an herbivore's primary predator should cause a decline in vegetation. That is not surprising, nor is it difficult to prove (you can track all three populations simultaneously). There is also a causal mechanism at work that can explain the effect without the need for new assumptions (Occam's Razor).

The efficacy of the TSA and our security measures, on the other hand, are quite complex and are affected by numerous causes. Changes in travel patterns, other nations' actions, and an enemey's changing strategy all play a big role. You can't ignore all of these and pronounce our security gimmicks (and really, that's what patting down a 6 year-old is) to be so masterfully effective.
 
While this is true, we can't allow that technicality to wipe the slate clean. Our security as a whole is deficient, even if the TSA on its own might not be responsible for these two particular failures. Our tax dollars are still going to the our mutual safety so we should expect more.
As I said, I understood the point you were trying to make. But.... you can't take two non-TSA incidents and use those to make a case against the TSA specifically. All you can do is say that increased security, similar to what the TSA does, can be shown to not catch everything. I could just as easily argue that because the two incidents (shoe and underwear bombers) did not occur from TSA screenings then that is proof the TSA methods work. I could, but I won't because we don't really know that is true. Too small a sample to judge.
Well when a fanatic is willing to commit suicide because he believes that he'll be rewarded in heaven, 50/50 odds don't seem to be all that much of a deterrent.
Did you not read my post above? Or did you not understand it? Or did I not write clearly? I'll assume the 3rd. Past history is that bombs are not put on planes by lone wolf fanatics. They are placed there by a whole operation involving a number of people... perhaps a dozen, maybe? The person carrying the bomb may be a brainwashed fool (though, surprisingly - often educated) - but the support team likely aren't fools. The team includes dedicated individuals who have specialized training and experience that are needed to mount further operations. The bomb makers, the money people, the people who nurture the bomb carrier and ensure that they are fit (mentally) to go through with a suicide attack. These people, the support crew, are not going to like 50/50 odds. Nor, are the support teams command and control. The security forces have shown themselves to be quite good at eventually following the linkages back up the chain.
What's worse is that we've only achieved that with a lot of our personal dignity, time, and money. I don't think we can tolerate much more. We should be expecting more for the time, money, and humiliation we're putting ourselves (and our 6 year-old children) through.
You are right. There has been a cost to dignity, time and money. Most of life is. People are constantly balancing personal and societal security/safety against personal freedoms. In this case what you think is only part of the balance between society and security. You feel it's too far. I can't argue. I don't fly anymore unless I have to. But, I also think that what the TSA (and CATSA, & the European equivalents) are doing is working. I just don't have to like going through it.
....
Your statistics don't unequivocally prove the efficacy of the TSA though. They only show that the TSA employs a cost-benefit method to determine what measures to take.
Give the man/woman/boy a cigar! There is no way to prove it, other than setting controlled experiments in which make some airports security free, and others with varying levels of security. And in some cases you don't tell the travelling public which airports have what level (if any) of security - but you do tell the bad guys/gals.

In other words, in this world... all you've got is incomplete data to try and make a reasonable decisions based on a cost/benefit analysis.
Since you believe in the efficacy of the TSA so much, the burden is yours to make a clear and convincing case, not mine. I can provide alternative hypotheses, but I am in no way saying that these are provable at the current moment in time.
I did. I cited a sharp drop-off in hijackings at a particular moment in history. Within the limits of a Mac Rumours Forum, that is as far as I'm going to go. If you an alternative hypothesis, you have to at least back it up with something. My something trumps your alternative hypothesis - even if my something is merely a pair of deuces - until you provide something to back up your AH.
I'm only saying that they are rational objections to your theory.
Objections with nothing to support them.
My hypothesis is essentially the same as Lisa's: the protection is coming from our circumstances rather than our deliberative efforts.
Good. Support your hypothesis. Otherwise it's got the exactly the same weight as my hypothesis that in fact Lisa's rock was making the bears scarce.
Terrorism is a complex thing. My bet is that as we waged wars in multiple nations, it became more advantageous for fanatics to strike where our military forces were.
US has been waging wars in multiple nations since.... well, lets not go there.... for a long time. What changed on 9/11? Besides enhanced security at the airports, that is.
Without having to gain entry into the country, get past airport security (no matter what odds were), or hijack a plane, terrorists were able to kill over 4,000 Americans in Iraq and nearly 1,500 in Afghanistan. That's almost twice as many as were killed on 9/11.
Over 10 years, not 10 minutes. It is the single act of terrorism on 9/11 that is engraved on people's (not just American) memories and consciousnesses - not the background and now seemingly routine deaths in the military ranks (I'm speaking about the general population, not about the families and fellow soldiers of those who have been killed.)

Terrorism against military targets is 1) not technically terrorism, and b) not very newsworthy to the public. That's why terrorists target civilians. Deadliest single overseas attack on the US military since the 2nd WW - where and when? Hint... it killed 241 American serviceman. Even if you know that incident, do you think it resonates with the general public in anyway? How about the Oklahoma City bombing? Bet you most people would think more people were killed there than in .... (shall I tell you? Beirut.) That's because civilians were targeted in OK, and the military in Beirut.
If I were the leader of a group intent on killing Americans and Westerners in general, I certainly would go down that route rather than hijack planes.
You'd not make the news very often, nor change much public opinion in the US, then.
It's pretty clear that it was not the rock.
But can you prove it? :)
Ecosystems are constantly finding new equilibriums; killing off an herbivore's primary predator should cause a decline in vegetation.
I'm glad you got that reference. The Salmon works like this. For millennia the bears and eagles have been scooping the salmon out of the streams. Bears, especially, don't actually eat much of the fish. They take a bite or two of the juiciest bits (from a bear's POV) and toss the carcass over their shoulder to scoop another Salmon. All those carcasses put fish fertilizer into the creek and river banks. A lot of fertilizer. So, the you get really big trees there.
That is not surprising, nor is it difficult to prove (you can track all three populations simultaneously). There is also a causal mechanism at work that can explain the effect without the need for new assumptions (Occam's Razor).

The efficacy of the TSA and our security measures, on the other hand, are quite complex and are affected by numerous causes.
But I think your reasoning is flawed. Human behaviour is much less complex than tracking how the ecosystem interacts with itself. One species vs numerous species; A species we can communicate with vs multiples that we can't; A long history of trying to understand human behaviour vs Not so much.
Changes in travel patterns, other nations' actions, and an enemey's changing strategy all play a big role. You can't ignore all of these and pronounce our security gimmicks (and really, that's what patting down a 6 year-old is) to be so masterfully effective.
It's also why they couldn't pay me enough me to run that operation. Too many "known unknowns".

We can't deduce anything from that footage of the 6 year old without knowing more. What if the explosives sniffing machine was going nuts anytime the girl went near it. If you were on that plane, wouldn't you want to know why that machine thought the girl has explosives on her? We don't know that there was a explosives sniffing device, and we don't know that there wasn't. All we know is from that footage that doesn't give us any context.

If I was a privacy or rights group, I would immediately launch an inquiry though. There is a enough information to be concerned, just not enough to form any conclusions what-so-ever. Except the screener appeared to be very professional.

The OP was ambiguous ... I read it that the weapons used on 9/11 were still not banned. As opposed to not banned at the time.

Hasn't anyone noticed that not a single US plane has been hijacked in the past 10 years? A quick look at Wikipedia shows 7 US planes hijacked in the 1970s, several in the 80s and 90s. Four planes were hijacked in 2001 (all on the same day....) - and then not a single US, European, Japanese plane has been hijacked.

Something is working.....

1980s - Aer Ligus Dublin - London; Air France Frankfurt - Paris; Rio Airways Killen, Texas - Dallas, Texas; TWA Athens - Beirut; Egypt Air Athens - Cairo; Malev Hungarian Airlines Prague - ?? ;

1990s - Lufthansa Frankfort - Cairo; FedEx flight Memphis - ??; Air Malta Malta - Turkey; All Nippon (domestic flight);

I've only listed those flights that departed from a European (and one Japanese) airport.... not European airlines that departed from non-European airports. After 9/11 there were still a number of hijackings, but the closest they come to European departure points are Nicosia, and Tirana. Though there was one from a Mexican Airport and one from a Caribbean airport. The Mexican hijacking was by a man threatening a bomb, but I don't think they actually found one.

I'll grant you the eighties. Now we get in to the ninties and there's...one in the United States, and it's an employee hijacking a company plane (FedEx).

So what's the correlation you're going for here? I'm not seeing it.

I see a decline from the 70's to the 80's, but the 90's seems in line with 2K.

We go ten years without a single commercial U.S. flight getting hijacked. Then 9/11. Then ten more years without. I'm not seeing some amazing statistical shift as a result of TSA. Further, I'm not seeing anything that justifies the new full body scanners. These were added without any supporting reasons.

If your argument is that security changes post 9/11 have made things better than the previous decade, I think showing it via statistics will be shaky at best. Zero passenger-carrying hijacks in the U.S. in the decade before 9/11 followed by zero passenger-carrying hijacks in the U.S. in the decade after 9/11 is not a statistic you can make a very solid conclusion off of.

And if your argument is that last year's full body scanners are justified, I would request much more evidence.


And how may people have the TSA found?

You tell me.

And how many people have not even bothered to try, because they were afraid of getting caught?

Same number as in the 90's.

My only claim is that something the TSA is doing is working to help prevent hijackings. This was in response to some arguments that nothing airport security was doing was in fact useful. If you go back, you will see I quoted both TSA and European stats, not just TSA. And that while there may have been no passenger hijackings in the 90s in the USA, there were a couple in Europe, and one in Japan. And then nothing in Europe and Japan or the USA since 9/11. Which I believe is due to increased airport security, similar to what the TSA does.

That's all I'm saying. I'm not advocating for the current screening, just refuting some baseless arguments that it's a total waste of money ("baseless" as in - "it's my opinion, and I'm not presenting any evidence to support it"). Opinions are fine, and everyone is entitled to them. Just don't expect me to accept an opinion as fact, if I can support my opposing opinion with at least some evidence.

(I'm using Japan and Europe 'cause they also have a tradition of terrorist organizations targeting their planes, and because they "harmonized" their screening standards to the TSA. No choice, if they wanted to continue flying their planes into or over US airspace. Other countries may have also harmonized (like Canada) but either they don't have a tradition of terrorism, or I don't have enough info about them.)

Alright, we might be perceiving each other's arguments differently and arguing semantics in that case.

I have no issue with airport security besides the last two years' increase. I feel the body scanners and pat downs on opt out are unnecessary wastes of time, money, and personal privacy.

I have no issue with other aspects of post 9/11 airport security. I fly all the time and never found it worth giving a thought before the recent implementation.

Well actually we know the TSA methods don't work because both of the incidents were from European airports that mirror what the TSA does. Added to the number of weapons that make it through TSA checkpoints, it's easy to see that the TSA does in fact not work to the extent that it is expected to.

These people, the support crew, are not going to like 50/50 odds.

I understood your rather simplistic attempt at game theory just fine. The problem remains that one side is not a rational actor. The command portion of terrorists have virtually nothing to lose with a botched attempt, and neither does the fanatic patsy. A 50/50 ratio isn't good enough for our security because the downside for both command and patsy are much smaller than the upside (from their perspective). The chances of failure need to be much higher in order to effectively deter terrorists.

You are right. There has been a cost to dignity, time and money. Most of life is. People are constantly balancing personal and societal security/safety against personal freedoms. In this case what you think is only part of the balance between society and security. You feel it's too far. I can't argue. I don't fly anymore unless I have to. But, I also think that what the TSA (and CATSA, & the European equivalents) are doing is working. I just don't have to like going through it.

Sacrificing these things is appropriate when there is a tangible gain. There hasn't been much of a tangible gain with TSA, and this is coming from the head of Israeli Security. We're paying a lot and getting almost nothing in return. Every year there's a new "standard" put out there to make it seem like TSA is doing something, but time and again security experts have lambasted TSA and its efforts as a dog and pony show.

Your own opinion of flying should be an example of how ridiculous things have gotten. If people now become disgruntled and irritated every time they fly, for perhaps marginal gains in security, then our methods have failed.

Give the man/woman/boy a cigar! There is no way to prove it, other than setting controlled experiments in which make some airports security free, and others with varying levels of security. And in some cases you don't tell the travelling public which airports have what level (if any) of security - but you do tell the bad guys/gals.

It is difficult to prove, but you can make an educated guess about what the cause is. Other than the correlational evidence, there is no other good data to suggest that TSA has actually been effective. In no field is correlation enough to establish anything but correlation.
I cited a sharp drop-off in hijackings at a particular moment in history. Within the limits of a Mac Rumours Forum, that is as far as I'm going to go. If you an alternative hypothesis, you have to at least back it up with something. My something trumps your alternative hypothesis - even if my something is merely a pair of deuces - until you provide something to back up your AH.

No, that's not how it works. If you want to assert your idea as correct, the burden is on you to show that it is correct. I am going to try to poke holes in your reasoning, and it's up to you to show that my criticisms are invalid on the bases of logic and evidence.

So far you've only cited correlation, which is not sufficient evidence for causation. You ignored my criticism based on military intervention, changing travel patterns, etc, and only want to trumpet your belief that correlation is enough. It's not. If you don't want to do more on Mac Rumors, then don't post anymore on this topic concerning this line of discussion.

Objections with nothing to support them.

There's plenty to support my objections. The death tolls overseas over the past 10 years are solid evidence that Muslim extremists have been quite successful without aircraft.

Our changing travel patterns (fewer people are as willing to fly, and this was especially apparent when 9/11 was still fresh in our minds) are a good basis for a changed ratio of flights to potential threats. With a decade of declining passengers, and with hijackings being rare events to begin with (in the US, not the world as a whole), to go 10 years without a hijacking hardly seems remarkable. Prior to 9/11 the last notable hijacking in America was a FedEx plane in Memphis in 1994. Prior to that, it was 1985. In other words, long stretches of time without hijackings are actually quite common. In fact, hijackings have been on the decline since the 70s and 80s largely because airline insurance has mostly disappeared.

There is a lot more basis and evidence here than mere correlation.
Good. Support your hypothesis. Otherwise it's got the exactly the same weight as my hypothesis that in fact Lisa's rock was making the bears scarce.

No, the weight is different. I'm only trying to discredit the basis for your hypothesis (which is currently purely correlational).

Lisa's rock was not making the tigers scarce because the fundamental logic was flawed. There is no causal ability for a lone rock to prevent tiger attacks in the middle of Springfield. The hypothesis fails outright because it is logically impossible.

Your hypothesis, while not as horrible as an anti-tiger rock, needs more than just correlation to be possible. It isn't credible until you do more leg work to prove it. I'm not contending that any one of my ideas is the lead reason for a decline in airline security threats, I'm just saying that they are all plausible alternatives to a purely correlational argument like the one you're making.

US has been waging wars in multiple nations since.... well, lets not go there.... for a long time. What changed on 9/11? Besides enhanced security at the airports, that is.

What changed is that we took the fight to the terrorists home turf. It became drastically easier for suicide bombers to attack Americans when thousands of them were walking around. Our troop casualties are staggering (nearly 32,000 injured in Iraq in addition to the 4,000 dead and over 10,000 injured along with 1,500 dead in Afghanistan). The terrorists have been quite successful without the need for airline hijackings.

Even though they did not target American civilians, they did still kill and wound Americans and other Westerners (which was always their goal). For them the distinguishing characteristic is not civilian vs. military; it is heathen vs. devout follower.

But can you prove it? :)

Yes. Any moron with a rock and a tiger can prove it. The rock will do nothing agains the tiger. We also know it wasn't the rock because Springfield doesn't have tigers. There is no causal mechanism. The notion that the rock is effective fails right there.
But I think your reasoning is flawed. Human behaviour is much less complex than tracking how the ecosystem interacts with itself. One species vs numerous species; A species we can communicate with vs multiples that we can't; A long history of trying to understand human behaviour vs Not so much.

Except that we have a much harder time studying ourselves. Our interactions are lot more complex than predator vs. prey. Trying to figure out why humans are doing more or less of something is quite difficult, and you especially can't rely on correlation alone.
We can't deduce anything from that footage of the 6 year old without knowing more. What if the explosives sniffing machine was going nuts anytime the girl went near it.

I'll agree with you here. The agent might have been fully justified and without knowing more it would be hard to judge. However, it does leave a bad taste in one's mouth. Other more effective security agencies don't do this kind of thing (like Israel) and yet we're told that ours does. It doesn't inspire confidence.
 
Well actually we know the TSA methods don't work because both of the incidents were from European airports that mirror what the TSA does. Added to the number of weapons that make it through TSA checkpoints, it's easy to see that the TSA does in fact not work to the extent that it is expected to.
All we know is that increased security screening is not perfect. Perhaps you can extrapolate the European experience (in this case) to the TSA... but that's as far as you can go.

A 50/50 ratio isn't good enough for our security because the downside for both command and patsy are much smaller than the upside (from their perspective). The chances of failure need to be much higher in order to effectively deter terrorists.
Do you always start with the insulting tone (see bolding) when the debate isn't going your way? I would argue that both sides are rational actors, though both sides may also employ non-rational players. The higher echelons of terrorist organizations have shown themselves to very worried about being captured by the fact that they are so hard to catch. If they didn't care, they wouldn't be going to a great deal of trouble to avoid it. Therefore, to my mind, they are rational actors. That 50/50 number is one that I threw into the argument as an "for argument's sake". Please don't rely on it for anything factual. The TSA in fact catches more than 50% of their training/testing planted weapons. And yes, I think even if the the number was as low as 50/50 a rational actor would do everything... oh heck... I've already written all that - you've not presented anything else of substance in it's place, so I'll just save my typing finger....
Sacrificing these things is appropriate when there is a tangible gain. There hasn't been much of a tangible gain with TSA, and this is coming from the head of Israeli Security. We're paying a lot and getting almost nothing in return. Every year there's a new "standard" put out there to make it seem like TSA is doing something, but time and again security experts have lambasted TSA and its efforts as a dog and pony show.

Your own opinion of flying should be an example of how ridiculous things have gotten. If people now become disgruntled and irritated every time they fly, for perhaps marginal gains in security, then our methods have failed.
That's the funny thing. I've never actually said that the TSA is the best thing around. All I've said is that the TSA is doing something. That's all - that the TSA is doing something right. Not everything. Just something. Go back and look it up. Even the head of the Israeli security never said they were useless (as in doing nothing right). Just that it wasn't the best use of resources. Oh, and if you know Israelis (and I do), then you'll also know that there is another Israeli who knows just as much as that first fellow, and she thinks the TSA is doing things just fine.
It is difficult to prove, but you can make an educated guess about what the cause is. Other than the correlational evidence, there is no other good data to suggest that TSA has actually been effective. In no field is correlation enough to establish anything but correlation.
That's the problem with 90% of the decisions Governments make. All they have is correlational connections. Or incomplete causal relationships. Or... basically the best they can do is make an educated guess, and hope for the best.
No, that's not how it works. If you want to assert your idea as correct, the burden is on you to show that it is correct. I am going to try to poke holes in your reasoning, and it's up to you to show that my criticisms are invalid on the bases of logic and evidence.
No, on two counts. 1) You asserted "Our attempts at security are at best as good as Lisa's rock...". I countered your assertion by saying that the TSA must be doing something right, and used the stats on hijackings. I (to paraphrase you) "poked hole in your reasoning". You've presented nothing that counters my evidence, except to try mocking it as simplistic. If it is, then show how it is.... If my argument doesn't convince you. Then say so, and then leave it at that. I have my opinion, you have yours. But if you want me to change my opinion you had better do better. 2) I've forgotten - cr*p.
So far you've only cited correlation, which is not sufficient evidence for causation. You ignored my criticism based on military intervention, changing travel patterns, etc, and only want to trumpet your belief that correlation is enough. It's not. If you don't want to do more on Mac Rumors, then don't post anymore on this topic concerning this line of discussion.
You are right correlations don't show causation. But they are evidence for it. If you have evidence that shows otherwise, present it.

I didn't ignore your criticism on military intervention. In fact I addressed it at least twice, and even slipped in minor dig at American hegemony. Go back and read my post again. I recognize that these are starting to get a bit long, so it's easy to miss things.
There's plenty to support my objections. The death tolls overseas over the past 10 years are solid evidence that Muslim extremists have been quite successful without aircraft.
I'm not sure of your point here. If you mean the military death toll, then I would argue it's not the same thing. The military are in those theatres precisely because the terrorists were successful at killing civilians. Plus the groups fighting the in Iraq, Afghanistan, etc are not the same groups as those aiming at aircraft and other civilian targets. The muslim extremists killing soldiers might also just be trying to repel an alien invader.
Our changing travel patterns (fewer people are as willing to fly, and this was especially apparent when 9/11 was still fresh in our minds) are a good basis for a changed ratio of flights to potential threats. With a decade of declining passengers, and with hijackings being rare events to begin with (in the US, not the world as a whole), to go 10 years without a hijacking hardly seems remarkable. Prior to 9/11 the last notable hijacking in America was a FedEx plane in Memphis in 1994. Prior to that, it was 1985. In other words, long stretches of time without hijackings are actually quite common. In fact, hijackings have been on the decline since the 70s and 80s largely because airline insurance has mostly disappeared.
...
Yes, that I can almost buy. I'm not sure where you are getting your stats from, though. I see no US hijackings in 1985. But you are correct that the rates of hijackings were lessening up through the 1990s. However there were several European and one Japanese hijacking in the decade prior to 9/11, and none since 9/11.
No, the weight is different. I'm only trying to discredit the basis for your hypothesis (which is currently purely correlational).
Actually, I started off my trying to show your hypothesis was incorrect. (That the TSA was as useful as Lisa's rock)
Lisa's rock was not making the tigers scarce because the fundamental logic was flawed. There is no causal ability for a lone rock to prevent tiger attacks in the middle of Springfield. The hypothesis fails outright because it is logically impossible.
But you still have not proven Lisa's rock is not making the bears scarce. How about.... There are rocks just like this one where there are bears (I'll concede that you can go and find those rocks and those bears).... therefore it appears that this rock and the lack of bears is just a coincidence. It may be "logical" to assume that there is no causation, but when you have been challenged to prove it, at least make the attempt. And to actually prove it we would need to design an elaborate experiment that involved bears and rocks and moving machines, though we would need to be careful not to introduce any confounding factors. And yet, perhaps it was Lisa's rock. We often call things we don't understand "magic". Though, I will concede, it's probably not Lisa's rock. But, there is always the chance (slim as it may be) that it is the rock.
Your hypothesis, while not as horrible as an anti-tiger rock, needs more than just correlation to be possible. It isn't credible until you do more leg work to prove it. I'm not contending that any one of my ideas is the lead reason for a decline in airline security threats, I'm just saying that they are all plausible alternatives to a purely correlational argument like the one you're making.
Again. I'm not putting my hypothesis forward as the truth. I'm presenting it as a counter to your Lisa's Rock = TSA. You need to do the leg work to show otherwise.
What changed is that we took the fight to the terrorists home turf. It became drastically easier for suicide bombers to attack Americans when thousands of them were walking around. Our troop casualties are staggering (nearly 32,000 injured in Iraq in addition to the 4,000 dead and over 10,000 injured along with 1,500 dead in Afghanistan). The terrorists have been quite successful without the need for airline hijackings.
Different groups. One group (Al Queda) targets civilians. The other group(s) - mostly Taliban - are fighting what they see as invaders.
Even though they did not target American civilians, they did still kill and wound Americans and other Westerners (which was always their goal). For them the distinguishing characteristic is not civilian vs. military; it is heathen vs. devout follower.
It's where the "heathens" are .... in muslim lands. Notice that the Taliban are not attacking much outside the Muslim lands.
...
I'll agree with you here. The agent might have been fully justified and without knowing more it would be hard to judge. However, it does leave a bad taste in one's mouth. Other more effective security agencies don't do this kind of thing (like Israel) and yet we're told that ours does. It doesn't inspire confidence.

Yes... it does leave a bad taste in the mouth. My head could go through the exercise of trying to keep an open mind, in case there were circumstances we don't know about. But my heart went out that child and her parents. And the agent. She knew she was being taped, or at least that she might be. I doubt she really wanted to do this either. Sigh.

Sorry to be the insensitive bastard, but 32k injured is hardly staggering. This isn't even comparable to a real war-time situation; 4k dead soldiers is but a drop in the bucket relative to past wars, declared or otherwise.

Again, if you want to solve the security problem, excess scanners is not the answer; profiling is. It's not that hard.
 
The radiation dosage from any properly maintained active scanner is still orders of magnitude less than what you get from a 4-hour flight at 10 km. Go ahead and opt out of your full-body scans... if you're doing it for the "health" reason you're tilting at a very small windmill.

Just read this letters from 4 UCSF professors to Dr. Holdren (advisor to the president) regarding the as of yet not proven harmlessness of the X-ray backscatter devices (http://www.npr.org/assets/news/2010/05/17/concern.pdf). Just to name a few: low dose radiation with high dose administered to the skin. Real photon Flux is not known. And - who is controlling the scanners and how to you know they are properly maintained? I am a radiologist and nuclear medicine physician and we have to report every dose the patient receives (X-rays and nuclides) - here you don't know the deposited dose. The letter is a good read and should be made much more public. The link is through NPR thankfully...

What security problem?

You know what kills more Americans than terrorism every year? Peanut allergies. Swimming pools. Deer running in front of cars.

Pat downs, body scanners, and TSA in generally are about "security theater." The government puts on a big show so the poor little sheep who are afraid of the big bad muslim wolves feel better.

So how about we all stop letting politicians play on our fears, stop feeding money to the contractors who design useless crap like body scanners and stop giving up constitutional rights all in the name of preventing a "danger" that's significantly less likely to kill you than a lightning strike.

That's exactly my point -- if you profile, not only do you not need all that equipment, but security could arguable be better than the current system which has well documented relapses and issues associated with it.

I believe that's faulty logic. Using seat belts has cut the number of fatalities for car passengers by 50% to 75% (depending on the rate of seat belt usage in a jurisdiction - USA/Canada). Because very few people are now killed in car crashes, you are saying we should stop enforcing the seat belt laws?

Or because so many fewer people are now dying due to drunk driving we should stop enforcing those laws?

I'm not sure your logic supports your conclusion.
 
I find it highly unnecessary for the TSA to pat down kids, especially, kids younger than 8-9 yrs old.

When was the last time we ever heard of a toddler shoe bomber?


They are horribly inappropriate, one "questionable" TSA lady groped my sister's boobs one flight, as if, last time I checked there are no records of people hiding crap in their boobs.

I understand the intent may be safety, but measure the risk peoples.

Agree on point one.

C-4 can be hidden in breast implants.

Unless the TSA "lady" was butch, I would not concern yourself. ;)
 
It's their job, we just have to deal with it. A few months back, a TSA agent groped my junk. I joked with him, "Linger any longer and you'll have to buy me dinner.";) He didn't even crack a smile.

Probably the 5th time he heard that crack that shift. :)

I wonder what comment would actually get them to crack a smile. Sort of like baiting the Guards at Buckingham Palace to crack a smile.
 
Patting down children is ridiculous. Anyone who's angry enough to blow up their own child on an airplane isn't going to be deterred by what we all sarcastically refer to as TSA "security".

How about we stop giving people reasons for blowing up planes? That would be easier and cheaper, but would also require an unwanted soul-searching moment for our entire society.
