Leo Getz

Leo Getz enters as a federal witness forced under Riggs and Murtaugh's protection, and every joke irritates them. He explains how the gang launders money and leads the pair to the South African group. After surviving an attempt on his life, he helps Murtaugh stage a scene at the consulate that draws anti-apartheid protesters. Later he is kidnapped by Rudd's men, and the duo go to the harbor to rescue him. He knows how the scheme works because he has laundered money for drug smugglers, which is why he becomes a federal witness.

Leo helps Murtaugh sell his house. He recognizes Jack Travis from old business deals, which gives the duo their first lead to identify him. At a hockey game, he is wounded when Travis escapes. Leo also mentions a warehouse where Travis stores arms shipments and, later, points to a housing development linked to one of Travis's shell companies, which becomes the climax setting. At the end, Murtaugh tells his family and Leo he won't sell the house and stays on the force beside Riggs.

In the fourth film, Leo joins the effort against an immigrant-smuggling ring and serves as a distraction when the pair question the boss Chan at the dentist's office. The laughing-gas scene ends up revealing the truth about Rianne and Butters. At the end, Leo and Riggs learn Lorna is about to give birth and race her to the hospital. What they get at the dentist's office helps the duo find out who the "Four Fathers" are, the prisoners the triad wants to free.

Leo Getz was a minor character with a single scene in Shane Black's original draft. Joe Pesci built him up in films 2, 3 and 4. In the Fox series, Thomas Lennon played the part as a recurring role across all three seasons.
