Perhaps not...I do wonder though, what exactly constitutes a "confirmed" sighting in the police's viewpoint? The line struck me because it could have easily just been "the last sighting of the Batman", but the word "confirmed" there added a tinge of ambiguity, even if it's just police jargon. It immediately made me wonder...well, what about unconfirmed sightings? I love Batman Beyond, and you're right. That's why I said one foot in the door...I guess what I am saying is it would make more sense for there to be a gradual decline there. I don't think he just closed up shop immediately. Lines like "The Batman wasn't needed anymore...we won" suggest that Bruce didn't think of himself as "retired" until that legislation was passed. I really felt that was the impression the movie was trying to convey.
