When a pickup truck came down from the other side of the bridge with a Confederate flag on its bumper and its windows down, the occupants engaged protestors, who shouted into the window. The driver, a grey-haired white man, leaned out and screamed back, but drove away when West Palm cops approached, flanking out in front of the street to keep it clear for cars trying to get to or from the Red Cross gala at Mar-a-Lago. It was the second time I thought about concealed carry.
