Mac: This could have been an accident.
Gunman Joe: No, it wasn't an accident. I'm not gonna let you pin this murder on me.
Mac: Calm down, Joe. No one's doing that.
Gunman Joe: You don't think I know what's going on out there? Your friends are out there trying to figure out a way to get in here without killing a lot of innocent people. They don't give a damn about me. 'Cause they think I'm a murderer. And you know what that means? That means they'll put a bullet in me the first chance they get. That's why I'm not leaving here until you prove that I didn't pull that trigger. And if I'm not leaving, nobody's leaving.
