Right now, Boston cops are shitting on the 4th amendment by searching people's houses without permission or search warrants.
I don't even think they are terrorists. They are just angry people. Terrorism would mean they have some sort of political or combative agenda...and are repping some group/religion/political persuasion, or whatever. They just seem to be like the columbine shooters, or virginia tech...bat-shit craziness.
But of course, they are going to claim they were legit "terrorists". If so, Russia is probably going to be annoyed.
