You're talking out of your ass.
He won't serve 90-days... if he does, it'll be min. security, house arrest or half-way house type situation I'm sure.
The probation and counseling are appropriate.
Thing that is a head scratcher for me. 8 hours of community service?
How skipping the 90 days of meaningless jailtime and give him 2160 hours of community service (90 days x 24 hours) that has to be served at a battered women's shelter.
First of all, since he'll be serving time in jail, not prison, there is no such thing as minimum or maximum security. There's just jail. It's the same for everybody. And LA County's main facility, the Twin Towers, is no joke. Unless he PC's up, he'll be spending his 90 days in a 80 man cell full of gang bangers, drug addicts, and murders awaiting trial.
Speaking of those 90 days, since his crime is violent in nature he would be ineligible for any sort of work release program, house arrest or anything of the sort. I'm not certain, but I don't even think he is going to get credit for good behavior. I'd be willing to bet good money that he'll be serving the full 90 days in one of the worst facilities in the nation.
This isn't the 80's or something bro. His lawyer might have gotten him the most favorable outcome possible, but California's DOC takes violent and domestic abuse sentences VERY seriously, and his semi-celebrity status will not buy him any sort of preferential treatment out here.
