Mr. Monk and the Three Julies - S6-E13
Factual error: Monk deflects the policeman's rifle shot and the bullet hits Stottlemeyer's car. But the gun fires just as Monk pushes it aside, and the car is behind them. There's nothing that could deflect the bullet back toward them, so at that angle, there's no way the shot could have struck the car. (00:35:50)
Answer: The two men are trying to work out a secret deal between them without involving the union, which means the workers' interests aren't being represented and defeats the whole purpose of a union. The mayor would lose labor's support and Cusack's union troubles would just be starting.
