Joseph Wambaugh, the former LAPD officer who brought realism to the "Police Story" TV series and books like "The Onion Field," died Friday.

In novels like “The Glitter Dome” and nonfiction works like “The Onion Field,” he took a harsh, unglamorous look at the realities of law enforcement.

He wrote 'The Onion Field,' 'The New Centurions' and 'The Blue Knight' and created the realistic anthology series 'Police Story.'
