Sharpers possible jail time looks light, but his parole restrictions are quite severe:

Looks like
- he has to snitch on everyone, all details, or he serves the full 20 years
- GPS monitoring in CA for 3-5 years, can't drive without permission, or travel more than 50 miles and must keep a detailed travel log. He will have a curfew.
- After CA, he will be transferred to Arizona where he will be on parole for life and must live where agreed. Can not leave the county without permission and will need written permission to leave the state. Can not move from Arizona ever unless approved by a Fed judge and agreed to by all jurisdictions that filed charges.
- No alcohol ever, no porn ever. Can't even enter an establishment having a primary business of selling alcohol; so no clubs and many restaurants might be off limits. No computer visits to porn sites, sex chats; etc.

Sharper will be high profile. In today's world, you can bet some watchdog group or individuals will be monitoring the authorities enforcements of probation terms, unless by then everyone has forgotten who Darren Sharper is.
