The problem with a law that covers too much is that it doesn’t cover anything very well. California has 109,000 registered sex offenders, but it couldn’t keep track of a convicted rapist on parole who was keeping a sex slave.

If California’s sex offender registration didn’t cover 109,000 people, including teenagers who took pictures of their teenage girlfriends, do you think the state parole officers and local cops might be able to keep track of convicted rapists on parole closely enough to notice if they’re keeping sex slaves?
