Sure it does, to the notional victims outside the prison walls who never have to deal with the violence these inmates unleash. Fact is many of these people are repeat offenders. At minimum it reduces the likelihood that these offenders will pop out little criminals.

As a deterrence for others though it makes little difference.

As sequestration OK.
