This chapter discusses criminal sentencing, including the philosophies that justify sanctions like deterrence, incapacitation, retribution, rehabilitation, and restorative justice. It also addresses mentally ill offenders and the insanity defense. There are two major sentencing models: indeterminate sentencing based on parole and structured sentencing using guidelines, determinate sentences, and presumptive sentencing. Mandatory sentencing and three-strikes laws are examples of structured sentencing. While the death penalty remains controversial, many states are reexamining it due to documented wrongful convictions.
