From the NY Times:
SANTA ANA, Calif., April 25 â€” Anyone convicted of a crime knows a debt to society often must be paid in jail. But a slice of Californians willing to supplement that debt with cash (no personal checks, please) are finding that the time can be almost bearable.
For offenders whose crimes are usually relatively minor (carjackers should not bother) and whose bank accounts remain lofty, a dozen or so city jails across the state offer pay-to-stay upgrades. Theirs are a clean, quiet, if not exactly recherchÃ© alternative to the standard county jails, where the walls are bars, the fellow inmates are hardened and privileges are few.
Many of the self-pay jails operate like secret velvet-roped nightclubs of the corrections world. You have to be in the know to even apply for entry, and even if the court approves your sentence there, jail administrators can operate like bouncers, rejecting anyone they wish.
