With black militancy on the rise, ghetto residents directed acts of anger at the police. Black residents growing tired of police brutality continued to riot. Some young people joined groups such as the Black Panthers, whose popularity was based in part on their reputation for confronting police officers. Riots among blacks occurred in 1966 and 1967 in cities such as Atlanta, San Francisco, Oakland, Baltimore, Seattle, Tacoma, Cleveland, Cincinnati, Columbus, Newark, Chicago, New York City (specifically in Brooklyn, Harlem and the Bronx), and worst of all in Detroit.
