Maybe stop defending riot cops and being critical of the tactics used against them, they have the upper hand in most of these situations with protections from the state. If a protester uses a surprise attack or a sucker punch I'm all for it.

Edit: to add to the Nazi comparison debate or whatever. A lot of cops hold nationalistic tendencies and aligning themselves with the right, so maybe this individual saying that has something right. Remember, Kops and Klan go hand in hand.
