From KERA:
Lawmakers in Austin who oversee the state’s sprawling prison system are concerned about state jails. These middle-tier facilities, which are for low-level felons with crimes related to underlying issues, were set up with the idea that they’d provide an array of rehabilitative services that would prevent future crime.
But state data show that, compared with state prisons, which house more serious offenders, and local jails, which house people who’ve committed misdemeanors, state jails do the worst at rehabilitating people.
