In page Stokely Carmichael:

"

Carmichael was present in Washington, D.C. the night after King's assassination in April 1968. He led a group through the streets, demanding that businesses close out of respect. Although he tried to prevent violence, the situation escalated beyond his control. Due to his reputation as a provocateur, the news media blamed Carmichael for the ensuing violence as mobs rioted along U Street and other areas of black commercial development.[1]
