Yes, an act of racism in protest of all the other murders of colored, unarmed citizens by overzealous police officers.  We the public have seen way too many raw videos taken by law abiding citizen bystanders of police shooting citizens in the back or while they're laying down with their face pushed into the ground and their hands cuffed behind their  back and shot dead.  That's what people of color are protesting.  Over 1,000 citizens have been gunned down by police officers across the country.  It never use to  be that way.  We can't ignore US Dept. of Justice investigations that racial profiling is at the core of citizen arrest murders.  It's the unarmed murders that can't be explained away.  If the shoe were on the other foot, and it was white people being gunned down in record numbers, I wonder if there'd be any protest.  We may never know because it isn't happening as frequently to white citizens to take notice.
