The United States relies primarily on incarceration as punishment. However, many states have sought alternatives to incarceration. Many states use short-term boot camps to rehabilitate first-time offenders. These highly regimented camps are intended to give offenders the discipline and respect for authority necessary to succeed in society. Other states and localities are experimenting with alternatives to imprisonment for drug offenders, such as treatment, probation, and work requirements. Others have supplanted long periods of confinement with a small dose of public humiliation and a variety of deprivations.
