This just in: Having sex with your daughter at her 18th birthday party isn't okay. Even if the jury deadlocks (twice) on the rape charges. It's still incest. You still go to prison. Even in San Berdoo.
Defendant makes a claim that Lawrence provides constitutional protection for the practice. Shockingly (not), Justice King rejects that contention. Consensual sex between adults is one thing. Dorking your teenage daughter is another. Know the difference. Learn it. Be it.
