Last night’s Ferguson protests in San Francisco got somewhat out of hand, with protesters smashing business windows and hurling bricks and bottles at cops. According to Beth Spotswood, cops donned riot gear “[not] to intimidate,” but rather protect themselves from hurled debris.

As the above video shows, they may have had a reason to be fearful. After a protester chucked a traffic barricade at a pile of cops arresting a person, one officer ran at the black bloc shot-putter, only to trip over the arrestee’s foot and fall on flat their face. Then again, SFPD officers can shoot someone in a park 14 times without serious repercussions.

Anyway, all the scene was missing was a slide whistle soundtrack.

UPDATE: A tipster sends us an extended video of the confrontation, including the moments leading up to the barricade throwing. In it, you can see a protester confronting an officer for unclear reasons, loudly shooting “fuck you” in his face. Then, after the officer bumps into the protester while walking past, another officer chokes the protester to the ground.

You can watch it yourself, starting around 2:15:
