In a lot of places, the damage in a situation like this is actually done by street trash and other community organizers, err, 'hangers-on,' not real students, but with UC Berzerkley the place is stupid enough that they could well be the spoiled brats who are supposed to be benefitting from Californistan's public ed system in the flesh.
Basically with about 200 of them it seems like that many police agencies should have been able to round up every one of the destructive little bastards and pack them into local drunk tanks, awaiting arraignment for felony mischief, conspiracy and arson charges.
