He rarely kills with a gun in his movies, actually. Most of the time, his characters use a gun as a last resort... Indy uses a whip 99% of the time, and shot a guy exactly once in 4 movies. He shot Greedo, but he was also a smuggler. The rest of the time he uses weapons, it's in self defense against storm troopers. Air Force One, I don't think he actually kills anyone, but they're all terrorists, so who cares. Blade Runner, he only killed murderous robots.
