Local news media happened to be present when a Bay Area Occupier on a building roof decided to start throwing bricks into the crowd below, presumably attempting to hit police officers.
He missed with the first one. The second time, someone in the crowd below wasn’t so lucky.
You can hear someone (another Occupier?) yell that the victim was hit in the face.
This was assault with a deadly weapon. Listen to how the news anchor tries to separate the Occupier from the rest of the movement by isolating him as fringe anarchist. Just like the “Cleveland Five” bridge bomb plotters, I’m sure.
The Tatler has more video from other angles, including what may be video of a second Occupy protestor throwing metal bars and concrete chunks from atop a nearby building.
