I think both shooting locations, the street and car dealership, are the same guy. Same clothes, same hat, same bag. Not sure which shooting came first, but the mob was clearly pursuing him in both videos.

The guy who got his arm shot stood back with his arms up at first. And he didn't get shot. But then he went to jump the citizen on the ground and earned it. I'm impressed the guy on the ground had the self control to only shoot the people who were physically in the act of jumpimg him.
