A Saint Louis cop, Dustin Boone, has been found guilty of a federal felony in the beating of a Black undercover cop whom he mistook for a protester. The black undercover cop told police that a group of uniformed officers "beat the f*ck out of him like Rodney King," even though he followed their orders. The protest where the black cop was undercover was itself in response to the acquittal of a white cop in the killing of of a Black man.
