Huey P. Newton co-founded the rebellious, activist group, The Black Panthers, in 1966. During the height of the civil rights movement, when Dr. Martin Luther King Jr. was preaching non-violence, Newton took more of a direct, revolutionary approach to his activism. As you can imagine, it didn't sit well with law enforcement. He was accused of shooting and killing police officer, John Frey, after being pulled over. Newton was convicted in September 1968 of voluntary manslaughter for the killing of Frey before having the conviction reversed and after having 2 mistrials, the matter was dismissed.
