Some people in this thread are so naive.
it is IN NO WAY the victim's fault. It would be his fault if he taunted them, or did something to provoke/cause the crime. He wanted to purchase an item, legal, and went to the seller's home upon request, legal, and was robbed, not legal in any way.
Because some scum thugs decided to point a gun at them and rob them is the fault OF THE ROBBERS.
People claiming it is the victim's fault are absolutely insane and make me sick. See if something like this happens to you - wonder how quick your tune will change.
unbelievable.
I don't think anyone here is blaming the victim in so far as they think the victim deserved to get robbed or that it was right for the robbery to take place. There is no question here that the thief is 100% in the wrong and the one committing an ethical and legal offense.
That being said. We live in the real world. We lock our front doors, children know to lock up their bikes. We don't run down the street with 6 $100 bills in hand yelling I've got $600!!
We all know that neglecting to take certain precautions can lead to dishonest people in the world taking advantage of us. Its sad, it shouldn't be this way... but it is.
Anyone who would advertise some item of value on an open internet forum, then meet in a private place with a complete stranger is not taking any precautions. I think that is all people are saying.
Don't make yourself an easy victim.
To the knucklehead with the pistol in his shorts: If you really think that is a good idea to walk into a dangerous situation just because you are armed, then perhaps you need to take a few advanced CCW classes, or visit a forum like defensivecarry.com
Self defense is first and foremost about situational awareness and not putting yourself into a bad situation. 95% of responsible CCW holders I know would never even talk about it...
Anyone bragging about how they are armed and think they can walk into any situation and defend themselves rambo style needs to grow up.
To the English guy: Thanks for being so diplomatic. Many of my european friends are alot more critical of US culture.

But for us the right to bear arms is more important than the danger the right may or not entail. Thanks for being understanding.
