Read villains their Miranda rights.
This made me laugh so much..... I don't think superheroes can just arrest people. Like when Batman just leaves a bad guy all tied up with a note on him. I don't think that $#!% holds up in court. "Well your honor. I have a note from Batman that says he did it." Or when Superman just drops of lex in the middle of a prison yard. Does Superman realize how the due process works?
