Whatever went on in L.A. on Monday it sounds like it wasn't your standard police/protestor clash.

Its possible to have a peaceful protest on any issue that you want. You guys can't do it because you're not peaceful, and not because the police are involved in some sort of right wing conspiracy with the man.)
