The most recent report about the state of realignment in California comes from the Public Policy Institute, which summarizes their latest findings (at this link):
" The county jail population did not rise nearly as much as the prison population fell, reducing the total number of people incarcerated in California. Realignment did not increase violent crime, but auto thefts rose. Research so far shows no dramatic change in recidivism rates. State corrections spending remains high, but there is reason to believe expenditures could drop in the future.
"Realignment has largely been successful, but the state and county correctional systems face significant challenges. The state needs to regain control of prison medical care, which is now in the hands of a federal receiver. And the state and counties together must make progress in reducing stubbornly high recidivism rates. "
