The Blue Meanies have done it again. Going around picking on innocent citizens who just want to exercise their Constitutional Rights to sell drugs, curse, intimidate, and choose what laws of the community they do or don't want to follow. (But they love the laws that protect "ME".) Yes, it's the cop's fault. It's not the crowd's fault that they chose to become violent in word and action. God forbid that they take responsibility for their own behavior. Poor things - victims once again. The Cops just MADE them act that way. 
Oh yes, let's bring the Homeless into it. That will generate some sympathy, even though the Homeless had nothing to do with it. But we can USE them as a way to justify cowardly mob rule. Too bad people don't understand that linking the Homeless in with this just further prejudices some people's attitudes toward the Homeless. 
Yes, I have my Rights! Just don't remind me of my responsibilities to the larger community. I may have to start giving rather than taking.
