Other mistake: An arsonist makes a telephone call to an accomplice. He dials only six numbers, not seven, and as soon as he finishes dialing the last number he says, "I have a job for you" and hangs up. He didn't allow any time for the other phone to ring and the person to answer.
Other mistake: T.J. Hooker and Vince Romano pursue two men who robbed the box office during a Beach Boys concert. The action takes place in the lobby of the Los Angeles Sports Arena, which is an indoor venue, but the footage of the Beach Boys performing is from an outdoor concert.
