Incapacitation is a very pragmatic goal of criminal justice. The idea is that if criminals are locked up in a secure environment, they cannot go around victimizing everyday citizens. The weakness of incapacitation is that it works only as long as the offender is locked up. There is no real question that incapacitation reduces crime by some degree. The biggest problems with incapacitation is the cost. There are high social and moral costs when the criminal justice system takes people out of their homes, away from their families, and out of the workforce and lock them up for a protracted period. In addition, there are very heavy financial costs with this model. Very long prison sentences result in very large prison populations which require a very large prison industrial complex. These expenses have placed a crippling financial burden on many states.
