But is Harvey Dent as important as 9-11? Thousands died. I think thats a bit of a stretch, what did he really do for Gotham?
For starters he lied about being Batman, causing millions in damages to the city, millions in damages to vehicles and helicopters and the loss of life all over a plot to trick a terrorist that ended up backfiring and resulted in the destruction of a police station and several more officers dead. He supported the vigilante they now all blame for all their trouble more then anyone else publicly.
He attempted to prosecute several hundred criminals at once, which is so ludicrously an abuse of the justice and legal system to group murderers in with guys that were simply a chauffeur for a mob figure and tri them togeather. And then as Gordon pointed out, most of them were set free anyway costing the city even more in having to jail them, clothe them, feed them for a short period.
He did murder several people, and took Gordon's child and wife from their home and and put a gun to his son's head and was about to blow his brains out. I can't imagine Gordon sticking up for him when in reality he was a pretty big failure in the what, 2 months he was in Gotham?
