Batman Begins was ass. But Dark Knight was full of more plot holes than LotR. If Buttman can't kill the Joker cuz of his morals, then CAGE the fucker.

And NO ONE has explained why, after Batman knocks out The Henchmen at the party then dives out to save Katie Holmes, WHY THE HUNDREDS OF GUESTS JUST STOOD THERE AND LET THE JOKER SAUNTER OUT?????
