I'm a BU student, but definetly not a troll, so take my word on this . . .
They were not at a bar, they were at a house in a residential area popular with students just off of campus. In fact they were only a couple of blocks from Walter Brown Arena . . . although there may have been a fight previously, the four people attacked had nothing to do with it . . . they were attacked out of retaliation for an incident they were not involved in; they just happened to be there when the assailants returned with weapons. They broke no laws whether set forth by the state, city, university, or athletic department, and yes they deserve justice.
On a brighter note, I will be at the Devs - B's game on Saturday, and should be able to post some pictures of Parise, Zajac, and Hale for anyone interested, in the former players thread.
