That's the thing though. The shear population size of the USA means that the NSA would not have people just looking through your messages and other personal data willy-nilly. There would be an element of suspicion in place before resources were devoted to such a venture.
I think a lot of people would consider themselves a bit of a special and unique snowflake. When in fact, the NSA has absolutely no interest in the vast majority of the population. For investigative purposes the general population is essentially noise that needs to be filtered out when performing investigations.
The level of access the NSA are pushing for are to allow investigations of interest to take place. Not to steal people's selfies and read their shopping lists.
If there's too much data to be usefully sorted through, then why is the NSA collecting all of it? Isn't that a waste or energy, time, money, and manpower?
If some sort of system is being used to filter and sort through it all, looking for patterns ("data mining"), what guarantees do we have that the system is even working? How many false positives are there? How many false negatives? We know that the NSA's mass warrantless collection of data on the American public has not prevented terrorists attacks such as the one at the Boston Marathon. It stands to reason there are also other people who are entirely innocent who are also placed under suspicion by this data mining program because it's imperfect. Without any transparency, we have no knowledge of any successful use of the programs, and so the program is by definition unjustified to the American public. Is this not a government for the people
by the people? How can we make good public policy decisions about a program that is so far-reaching in its impact but entirely secret? Hint: We can't.
If such programs are actually worthwhile, getting real results and with a minimum of collateral damage, then the American public would support them. That the government is so unwilling to even put these issues to vote is a sign that the American public would not support them if they were transparent. Likely they are rife with ineffectiveness and cost overruns. I'd like to know that, as a taxpayer.
I've heard the argument that we can't let "the enemy" know about these programs and how they work. Well if they're actually working, "the enemy" would surely notice all their plots being foiled, and their agents being arrested en masse. Knowing the capabilities of the US government to protect its citizens might even act as a deterrent. Security through obscurity is no security at all. You
have to assume your opponent is smarter and faster than you, and already knows all of your defenses. Surely if Snowden could take a massive load of top secret documents out of the country in such a spectacular, public way, "the enemy" can infiltrate the NSA and steal plenty of secrets in secret.
And look, absolutely nobody is saying that the government shouldn't be allowed to gather information on specific targets. People are just saying the government needs to prove to a judge that they have a valid suspicion about a specific individual, and limit the scope of their investigation to that specific individual. What the government is doing here is collecting information on everybody, treating everybody as suspicious, and heaven help you if their analysis targets you by mistake.
How would you feel about the police coming by your home every single day, searching it thoroughly for anything illegal, and never having to justify their actions or get permission from a judge? They also stick cameras in every room without telling you, and search the homes and cars of all your friends and neighbors. Got anything even remotely embarrassing or personal inside your home? Do the police have any reasonable cause to suspect you of anything at all? Wouldn't you feel even just a tiny bit harassed or oppressed, even if you weren't doing anything they can arrest you for? The digital equivalent of this scenario is happening right now. Where's your outrage?
