Looks like some Superman cop runs from behind the dark vehicle to stop the pursued vehicle in the snow [with his body] as it veers off the highway. He gets hit.
Then Rambo comes out of the woods and kills/murders the driver...while in a short-sleeved shirt.
From a better video, the Suburban swerved into the snow to miss the idiot cop, as reported on infowars earlier this evening. I don't know about the guys hands being raised or reaching for a weapon.
My take is that the cops were out to shoot someone, anyone that they could.
