I think that was a lady cop covering the first cop's six while he uh, subdued the guy while he was down.
Nice moves by the cops though, move up on them behind the cover of the bus and POW!
And it's nice to see the response of regular people who were trying to mind their own business before the hippies showed up. Certainly a lot of them, the regular people that is, vote Democrat and maybe they'll reconsider.
