some may move out of ca, most will stay for economic reasons and legal ones. Will some go underground, yep. However, how "underground" can you go? You sell your evidence right there. Look at this tape, no condom, ok, its company xyz. Follow the money... ahhh... there you are, busted!
Plus just wait till one girl gets an std and ends up sterile. She'll have a dozen lawyers ready to sue your ass before she's done with treatment.
