Roger Murtaugh is a Homicide detective with the LAPD and one of the two main protagonists of the Lethal Weapon film series along with his partner Sgt. Martin Riggs. Murtaugh is portrayed by Danny Glover in all four films of the series and carries a Smith & Wesson Model 19 revolver chambered in .357 Magnum as his main sidearm. He is well known for his catchphrases: "I'm too old for this shit" and "It's been revoked!" both of which are common staples of both Glover and the character, and have been parodied in numerous other films.
