Watch an Innocent Guy Get Shot with a Rubber Bullet By the Oakland Police for No Reason

If you watch the video, you can hear Campbell repeatedly ask the police if "this is okay?". I think it's safe to assume that Campbell was verifying with the police if it was okay to film them and if he was at a proper distance from the police line. He asks this question multiple times before continuing to film. Hearing nothing back, Campbell films the rest of the police line at a respectable distance until... he gets shot by an asshole police officer. What the hell? You can see the rubber bullet (bean bag? another projectile?) being fired and hitting Campbell in the video.
