Spoken like a true "compromiser". Just let them have their fun. Just let them go. "Boys being boys!"
If one is to have a relatively decent society, a society whose worst tendencies are contained by Law, if not by common decency and manners, this sort of thing must NOT be allowed to stand unchallanged. There is no "compromise" here. There is either a decent society or there is anarchy.
The really bad part? I suspect there will have to be a "Kent State" incident occur before the thugees "get the picture" that there really CAN be a down side to their counter civil behavior. Should such incident occur, bad for them (not that I would care much about them) and bad for the US.... as it would only bring us one step closer to a "Police State".
