"Dirty Harry, for example. Clint Eastwood was not a rogue cop. He was a maverick cop, but he was a good guy"

This quote by Charlton Heston is referring to the character Dirty Harry, played by Clint Eastwood in the 1971 movie of the exact same name. Heston is stating that although Dirty Harry was a maverick cop, he was still a hero. This suggests that although he was unconventional and often broke the rules, he still had a moral code and was eventually attempting to do the right thing. He was a law enforcement officer who wanted to take threats and flex the guidelines in order to finish the job, but he was still a hero. He was a symbol of justice and a champ of individuals. He was a maverick cop, however he was still a hero.
