Race Riot in San Quentin

Officials at California's oldest state prison, San Quentin, are trying to prevent an all out race war following the outbreak of rioting Monday morning between hispanic and white inmates which left 42 injured.

San Quentin was already on "lockdown" after a series of smaller brawls between white and hispanic prisoners broke out last week.

Earlier this year, the Supreme Court ordered California to abandon its policy of assigning inmates to racially segregated cells for as long as 60 days when they arrive at new prisons.
