Are we to believe that they don't fingerprint when you go to jail (Katherine and Marge storyline, Y&R)?

I know its all fantasy, but its my guilty pleasure. When Katherine was booked into jail, they took her fingerprints. This would have put the mystery about who she was to rest. I hate it that the writers want us to COMPLETELY check our brains at the proverbial door when we watch this show. What do you think?
