Dirty Harry's influence indentifiably extends beyond film, too. Castle doctrine laws (allowing the use of lethal force against home invaders) in some states used to be colloquially known as "make my day" laws, after an iconic line in one of the sequels. In context, the line heavily implies that Harry is motivated not by a desire to protect people from criminals, but by a desire to kill criminals.
