There was an analysis of Nolan and post-Nolan Batman that argued that once you strip away all the fantastic parts of Batman, all the Clayfaces and Mr. Freezes and Poison Ivies and the sentient robots and uncanny weirdness, all that is left is a bunch of problems that frankly the cops should be able to handle, and that Batman at that point is just a cop who is willing to violate people's Constitutional rights.

If Batman can be replaced by a well-outfitted SWAT team, then you're not writing Batman well enough. Give him some insane nonsense that cops are not equipped to handle.
