Is it certain these people are the actual culprits? I have a felling that might not be the case.
It’s what the media and government are saying. What other source of information do we proles have?
Nick, you saw video of two guys who look like Dzhokhar and Tamerlan carrying backpacks through the crowd. You saw the one who looked like Dzhokhar place a backpack where the second explosion took place. And, by now, you've heard several witnesses -- like the auto mechanic -- identify Dzhokhar and Tamerlan as, in fact, the guys in the video.
Plus, a month's supply of bombs were found in their living quarters and their car.
Yeah, they're the guys -- complete with motive.
