A Steph!Batgirl would be so hysterical. Thugs would get taken down, and when questioned by the police the conversation would be like:

Cop: So who did this to you Vinnie?
Vinnie: This girl, she was, like a bat, a Batgirl!
Cop: Can you be more specific, we got, like, half a dozen of those girls running around here.
Vinne: *shudders* Lock me up, officer, don't let them get me!
