Whether or not they get caught is up to you. We're leaving that one to your discretion!

And as for penalties... depending on how bad it is, it could be an assortment of: fines (sucks to be your bank account, man), banning from the casino, being kicked off the station (which the criminal can probably get around again after some time has passed), and... the police locking your account!! Which, has already been locked. So... yeah.
