As good as this scene is, the moments I'm waiting for in this upcoming movie are Batman's final showdown with the Joker and the iconic fight against Superman. We'll all get to see those when The Dark Knight Returns, Part 2 comes out on January 29th.
As this clip from the second part of the animated adaptation of Frank Miller's classic graphic novel shows, Batman's position on gun control has always been clear. Bruce Wayne thinks that nobody should have them. Given the trauma that lay in his past, you can't really blame the guy.
