police. He was the leading force in a shift in the military emphasis which focused on the overwhelming use of men, the use of tear gas, and an early, strictly enforced curfew. Police response Before the riots, John Layton, the police chief of Washington, emphasized that if there ever was a riot in Washington, he would use a large number of policemen with no guns, rather than fewer policemen with guns. During the riots, Layton put those words into action. Rather than acting immediately to the reports of rioting, looting, and window-breakings with a smaller force, he played the waiting game until a large enough force could be brought together.
