TDK ending was kinda weird to me. He took the wrap for killing Dent, that's a small sacrifice for a vigilante IMO not some huge profound shyt. The cops should have been chasing him for being who he is prior to that. It's like, "Aw shyt Batman's fukked up his publicity for the common good." So?
There's a big difference between him taking down criminals vs killing the district attorney tho.
I mean you right, but it's clear why the cops kind of let Batman pass up until that point - he was doing their work for them.
