Walter Hart Deaney was one of the principal villains of the movie Mitchell. He was a corrupt trade union lawyer. For several years, the FBI was working on a case against Deaney and his union for violating a large number of Federal laws. Deaney first came to the attention of Mitchell when Deaney shot an unarmed intruder who was busily burglarizing his house. When the cops arrived with Mitchell in tow to investigate the shooting, Deaney lied about how the burglar went for one of his guns and Deaney shot him in self defense. Mitchell quickly picked up on the fact that the burglar was way too short to reach the handguns in Deaney's gun case. While law enforcement processed the scene, Deaney got on the phone and asked his underworld contacts to have Mistretta talk to Gallano.
