Footage before this scene shows the guy chasing and trying to hit a black kid/adult with skateboard. Footage after this scene shows that he's not dead and being tended too/looked after by other protesters/looters.
He didn't die on the spot? Ah well that's OK then!
If he defends his property with a semi-automatic then he's the bad guy. He has no recourse to protect his livelihood. This violence must be stamped out with - dare I say it - whatever it takes.
