This is on the Champs Elysees in Paris. The man was chanting "Algerie Francais" as DeGaulle was riding up the boulevard.
There were Algerian terrorists in France at that time. These detectives dragged the guy around the corner and beat the daylights out of him before they took him away. I got zapped too for taking the picture, blindsided by another detective behind me. My two friends saw what happened and helped me.
