Why this scares me: What if this event in Boston is a test run for something bigger?
A better question, just what additional anti-terror laws will the US government impose because of this?
Whoever the suspect is I hope he/she is not a patsy like some of the supposed hijackers of 9/11 were (some of them were still alive AFTER 9/11) just so the US government can say 'the suspect came from Iran or Syria' or whichever country they're blacklisting, I really really hope events don't turn out like that and it was a crazed insane inhuman individual who carried out these wicked acts.
The last thing we need is for the US to retaliate and more injury, suffering and death is inflicted.
