Whatever the truth is, let's get this right.
The events in the videos were part of a protest against the Sept. 30 shooting of a black man, Patrick Kimmons, by Portland police. The protest began at the site of the shooting. Actual information on the shooting is scarce. Rumor is not.
PPD say they have video.
The fact that protestors spewed anti-white bigotry at commuters tells us, whatever else is true, they're dangerously confused.
Anarchists frequently argue that police are unnecessary. This is false. Simply, objectively, game-theoretically false. And the fashion on the authoritarian left is to see every police shooting of a black man as murder. Also false. Obviously.
