Did you see the guys youtube videos? Russia contacted the U.S. about one of the brothers, also the FBI did track that he was going to Russia and also interviewd him. They failed in not being able to act on the intelligence they had. The question is what are you willing to give up to go to that LA Laker game without worrying about terrorism or whether your parents will get home safely from the game. I am not trying to stand up for the NSA but i thing we need to come together understand what we want, what we willing to give up and always look at both sides of the situation.
I always think about the movie "Carlitos Way" with Andy Garcia, where he plays a ruthless gangster but he develops a conscience. One day this kid crosses him but instead of killing the kid, he gives him a break, then at the end as he is giving this life up and going straight, running to catch his train, this kid pops up and kills him. The U.S. has been this ruthless gangster through the cold war, securing energy supplies, etc, now Obama comes in and thinks he is going to give the U.S. a conscience but unfortunately some guy lost his mother, wife and daughter during Iraq or in another instance and he doesn't care that you have a conscience now. The bottom line is that the U.S. has to watch it's back for a long time because they made a lot of enemies on the road to become the "mob boss", super power of the world.
