When I see National Football League players kneeling in protest at football games while "The Star-Spangled Banner" plays, a searing image flashes through my mind.

A skinny black kid of maybe 18 is on his knees, hands in the air.  There's a cop standing behind him.  The kid is complying with all the cops instructions.  The cop is scared.  He fires at the base of the kids skill in a fit of rage.  Screaming. Blood everywhere. 

And I want to scream.
