DovidBT – Thanks to your post I looked it up. Basically the left started the whole thing – you can call it a left-wing conspiracy!

Add to that article the fact, later determined, that the chief of police specifically ordered his men to stay on the sidelines and “let them fight.” And the counter-protestors who were responsible for the violence were given trivial, if any, punishment.
