A single white Trump supporter who held up a sign and stood quietly as three dozen people surrounded him, smiling and screaming, snatching and pushing at him until he had to run for police cover. Someone grabbed his American flag and threw it on the ground and he fought to recover it. The police escorted him away.
Two young men, perhaps 17-19, standing quietly as they waited for a ride home.

Only once did one of those hats come down, and it quickly went back on again.
