Behind the scenes
The character (along with his magnum sidearm) is a reference to L.A Inspector Harry Callahan, protagonist of the Dirty Harry series of movies who it noted for using a .44 magnum as his weapon of choice as opposed to the standard police issue .38 caliber 6 shooter, and taking every 'dirty' police assignment that comes along. His character is noted for hating crime in every form and dealing with it not entirely by the protocols of the police force, or government.
