The former sheriff of Los Angeles County has been found guilty on charges of obstructing an FBI investigation into the abuse of prisoners in L.A. County jails, including the beating of prisoners who were handcuffed. Lee Baca ran the L.A. County Sheriff’s Department for 15 years and was one of the most powerful sheriffs in the United States. He now faces up to 20 years in federal prison on charges related to his attempts to thwart the FBI’s investigation—and then cover up his efforts.
