The Associated Press has a very good overview of the alleged Times Square bomber here: ["Times Square bombing suspect's life had unraveled"].
I'm going to refrain from commenting on this situation until more information is put forth. I'm sure all kinds of people will have all kinds of things to say about it.
But I do love it when journalists start to tell stories this way - allowing readers to get a bit of background into people. Isn't it odd that a lot of these alleged terrorists come from wealthy families? You would think that they would realize that they are a bit blessed compared to other folks (or, maybe, obviously, not).
No one will ever know why this guy unraveled - but thank goodness no one was hurt in this incident.
