'Rolling coal': Watch driver repeatedly smoke out anti-Trump and Elon protesters, and that's when things get much rougher * WorldNetDaily * by Joe Kovacs

A video provided to the Vallejo Sun shows a truck driver “rolling coal” at anti-Trump protesters in Vallejo last month. The resident who provided the video said the driver, who had no front license plate, drove up and down the street targeting the protest. Rolling coal is the act of intentionally tampering with a vehicle to emit large plumes of diesel smoke, often for the purpose of blasting pedestrians and bicyclists. #vallejo #protest #trumpprotest | The Vallejo Sun
