Behind the scenes
The character (along with his Magnum sidearm) is a reference to San Francisco 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 criminals and injustice in a way that is not entirely set nor endorsed by the protocols of the police force, or government.
