I think it is important to keep the actual alleged crimes in perspective. No one was killed. Of those who were injured, I believe 4/5 were treated and released the same day, and 1/2 were hospitalized overnight. There is no evidence at this point that the pipebombs were deadly. None.

What we are seeing in this thread is the sort of wild conjecture that rumor mills are made of. Because there is a small bit of video footage of the alleged smiling doesn't mean anything, except that some camera person got lucky and caught a fleeting moment on video which is now being used to try the suspect in the court of public opinion.

There is a high level of hysterical post 9/11 anxiety attached to this case, despite the fact it doesn't hold a candle to how many other acts of real, brutal violence have occurred across the US in the past week, in which real people were murdered, maimed for life, robbed of all their money/possessions, etc.

Get a grip people.
