The outside officers were also acting on direct orders from the FBI and not SPD or the city mayor in the case of the WTO riots. Having been in said riots where idiots dressed in black started smashing things, thus drawing in the FBI (and there's been numerous accusations over the years that the Black Bloc groups were also under FBI direction). Getting whacked by a baton while I was filming was not fun but I got whacked because the officer missed his actual target who was standing slightly behind me and had been busy throwing bricks and then dodging in behind other people.
