Motorist pulls gun on Black Lives Matter protesters attacking his truck. They were blocking road, and he tossed smoke grenade at them, cops say.

A motorist who was caught on video pulling a gun on protesters in downtown Savannah, Georgia, over the weekend was charged with aggravated assault,  WSAV-TV reported.

Police told the station a few dozen protesters angry about the Breonna Taylor case were lying down in an intersection and blocking traffic around 5:30 p.m. Saturday. Newsweek described them as "Black Lives Matter protesters" engaged in a "peaceful demonstration."

Video shows a dark pickup truck appearing to begin driving around the protesters — and then police told WSAV the driver tossed a smoke grenade at the group.
