They were The Mod Squad ("One black, one white, one blonde"), described by one critic as "the hippest and first young undercover cops on TV". Each of these characters represented mainstream culture's principal fears regarding youth in the era: long-haired rebel Pete Cochran was evicted from his wealthy parents' Beverly Hills home, then arrested and put on probation after he stole a car; Lincoln Hayes, who came from a family of 13 children, was arrested in the Watts riots, one of the longest and most violent riots in Los Angeles history; flower child Julie Barnes, the "canary with a broken wing," was arrested for vagrancy after running away from her prostitute mother's San Francisco home; and Captain Adam Greer was a tough but sympathetic mentor and who convinced them to form the squad.
