In the video after he kills the manlet someone tells him to call the police, he then pulls out his phone and makes a call, so hopefully there's a recorded conversation he has with a police dispatch.

I read, uncorroborated, that in that conversation he was instructed to go find the police that were posted at the intersection which is why he was running that direction.

Of course, we know the mob chased him down. He also immediately goes to the police and surrenders after the second exchange of gunfire.
