Adam-12 - Season 4 - Eps 1: Extortion
Malloy and Reed investigate an extortion racket against a group of Jewish Holocaust survivors, with the owner of a dry cleaners willing to testify but others not out of fear of retribution. The officers return to handle the owner's panel truck being set ablaze and later the owner is physically assaulted. Malloy and Reed capture both suspects. Other incidents involved a robbery at a bar (the perps escaped initially, but are later captured after a shootout), and a drunk man owed back pay by a dockmaster threatens to dump his boat onto dry land from a crane unless he's paid.
