All I'm hearing from you is that the rioting and looting is somehow justified. Police always gather in large numbers during potentially volatile situations - believe me, I've seen a MUCH bigger police presence during the while Occupy Wall Street protests here in NYC. Unless the police in that town actually attacked the protestors, there's absolutely no justification for the looting and rioting, which did absolutely NOTHING to express any points to the police there. The only people the looting and rioting hurt was the innocent business owners there, and the community which is now without that particular business servicing them.
