Well, L.A. worships its celebrities...they can get away with almost everything. Good for business, you know...

Kind of off-topic, but regarding OJ:
Back in my Hollywood days, my (now-ex) wife's best female friend was a nanny for OJ & Nicole, and Mel Gibson.
Her Mom was Nicole's realtor.
And my younger brother ran a valet service for an office building OJ frequented, including client parties.
So, I have it on pretty solid authority - several stories & observations - that Nicole was terrified of OJ & his temper, would exhibit bruises that she tried to cover up, and was trying to get away.

Don't think for a minute that all celebrities are perfectly sane and/or grounded.
To be fair, some are actually good folks, but there are some absolute wing-nuts in that sphere.
