Dept. of Rounding Errors

California's prison system is an embarrassment to the country—run largely by a prison guard's union that rivals only teachers unions for policy-warping mendacity in the Golden State, wracked (and intentionally segregated) by race-based warfare, overcrowded to the point where multiple federal judges are on the verge of issuing consent decrees that would free thousands overnight.

So it comes as both a surprise, and no surprise at all, that as many as 33,000 prisoners are serving sentences that actually expired, but went unnoticed due to clerical error. Money graf:

Corrections officials say they have been unable to calculate the sentences properly because of staffing shortages and outdated computer systems that force analysts to do the complex work by hand.
