Re: How long did Nolans Batman actually fight crime?(SPOILERS)
I think some people are being too liberal with this "last confirmed sighting" terminology. "Last confirmed" most likely implies that, as you would expect, people reported sightings that were false. You know, like how there aren't any "confirmed sightings" of Bigfoot.
I'm willing to bet he stopped going out as Batman after the night Dent was killed, and devoted his time to rebuilding the Batcave, in case Batman was needed again.
What difference do you think you can make, one man in all this madness?
