Prisoners and detainees of California

Huey Percy Newton (February 17, 1942 – August 22, 1989) was an African American revolutionary and political activist who founded the Black Panther Party. He ran the party as its first leader and crafted its ten-point manifesto with Bobby Seale in 1966.
Under Newton's leadership, the Black Panther Party founded over 60 community support programs (renamed survival programs in 1971) including food banks, medical clinics, sickle cell anemia tests, prison busing for families of inmates, legal advice seminars, clothing banks, housing cooperatives, and their own ambulance service. The most famous of these programs was the Free Breakfast for Children program which fed thousands of impoverished children daily during the early 1970s. Newton also co-founded the Black Panther newspaper service, which became one of America's most widely distributed African-American newspapers.
In 1967, he was involved in a shootout which led to the death of police officer John Frey and injuries to himself and another police officer. In 1968, he was convicted of voluntary manslaughter for Frey's death and sentenced to 2 to 15 years in prison. In May 1970, the conviction was reversed and after two subsequent trials ended in hung juries, the charges were dropped. Later in life, he was also accused of murdering Kathleen Smith and Betty Van Patter, although he was never convicted for either death.
Newton learned to read using Plato's Republic, which influenced his philosophy of activism. He went on to earn a PhD in social philosophy from the University of California at Santa Cruz's History of Consciousness program in 1980. In 1989, he was murdered in Oakland, California by Tyrone Robinson, a member of the Black Guerrilla Family.
Newton was known for being an advocate of self-defense and used his position as a leader within the Black Panther Party to welcome women as well.

Christian Devi Brando (May 11, 1958 – January 26, 2008) was an American actor who was one of the eleven children of actor Marlon Brando, and the only one Brando had with his first wife, former actress Anna Kashfi.
On May 16, 1990, Brando fatally shot Dag Drollet, the boyfriend of his half-sister Cheyenne, at his father's residence on Mulholland Drive in the Hollywood Hills. The family drama and trial were heavily publicized that year. He pleaded guilty to manslaughter and was sentenced to prison in 1991. He was released in 1996. In 2004, information introduced at the trial of Robert Blake for the 2001 murder of his wife, Bonny Lee Bakley, exposed Brando's relationship with Bakley and his possible involvement in her murder. In 2005, Brando pleaded no contest to spousal abuse of his then-wife Deborah and was given probation. He died of pneumonia on January 26, 2008, aged 49.
