Two of the guys he shot had guns. One had that gun pointed at his head and could have shot. He didn't and instead got his arm blown off.
I'm not calling the guys he shot heroes like some are b/c we don't know the details. If the girlfriend of one of the victims is to be believed, they were chasing him b/c he shot someone. We know he shot at least 3 people. There's only video of 2 of the shootings (on Twitter anyway). His first shooting appears to be what provoked the crowd to chase him down.
