I'm still waiting to hear when Batman/Keaton use a gun? And while I don't think the Joker/Nicholson fit the bill of what a true Dark Knight fan would have expected, I can still realize he did an excellent job.
Good point. But he didn't kill anybody with them. Although he did with the bombs that dropped off the wheels.
I also found it amusing in Batman Begins when he refuses to execute the Chinese farmer, but ends up killing a shit load of guys when Ra's al Ghul's house blows up because of him.
