Charlotte-Mecklenburg police Capt. Brad Koch has been a regular at Black Lives Matter marches over the past two weeks, mostly welcomed. But when he showed up at a Charlotte Uprising rally Monday, protesters swarmed him, demanding that he leave. He cupped his hand to his ear, then raised his hand, palm upward, as if to suggest he couldn't hear them. Moments later, a protester shoved him and they ended up wrestling in the grass. It’s a sign of the mixed reaction to Koch's presence at the marches.
