That's a pretty dishonest take on the progressive view of criminal justice.
Rehabilitation is just as important, if not more so, than punishment. Simply locking someone in a cage for a few years does nothing to prevent recidivism. It often makes it worse, as once someone comes out of prison, it can be extremely difficult to find work (since employers discriminate against felons), causing them to turn back to a life of crime in order to survive.
