I love TDK but...
So let me get this straight...you have a murderous psychopath who nearly killed the mayor, is out there kidnapping and killing COPS, and is causing mayhem in the streets...you somehow catch him but then at some point have him locked up with NO handcuffs and have only ONE person guarding him...no FBI, no hannibal lecter treatment, just ONE emotional guard and NO cuffs.
bruh he kidnapped harvey dent they needed info fast
im sure "storyline" wise he's at Arkham Asylum with straight jackets on now
