'Blue,' A New Book Looks at the History of the LAPD

Police shootings of unarmed black men, cell phone videos capturing all kinds of bad behavior by cops from Los Angeles to Ferguson, Staten Island and down to South Carolina -- it's all changing the way many Americans see law enforcement. In 1992, Los Angeles exploded into riots after four LAPD cops were acquitted of beating Rodney King. As the chaos spread, the police were mostly missing in action. Hard-nosed police Chief Darryl Gates stepped down, and his departure began a stop-and-start effort to reform the LAPD. We talk with journalist Joe Domanick, who captures that history in the new book "Blue: The LAPD and the Battle to Redeem American Policing."
