Dangerousness and Incapacitation: A Predictive Evaluation of Sentencing Policy Reform in California - Kathleen Auerhahn - Sponsoring Agency: US Dept of Justice, National Institute of Justice, United States. This predictive evaluation of sentencing policy reform in California concludes that the State's "Three Strikes" law will not be effective in incapacitating dangerous offenders, and it recommends alternatives to guide policymakers in constructing and implementing sentencing policies that will effectively target and incapacitate dangerous offenders. Abstract: In discussing the history of efforts to predict "dangerousness," this study notes the limited success of these endeavors. Sentencing innovations such as Three Strikes and Truth in Sentencing aim to select the most dangerous offenders for lengthy incarceration, the net effect of these laws may be a reduction in the aggregate level of dangerous offenders in the prison population, as more dangerous offenders who are not subject to mandatory minimum sentences are released to make room for "Three Strikes" and other mandatorily sentenced offenders. The first two of the scenarios accept the fact of an aging prison population and examine ways to focus the Three Strikes law more narrowly on particular types of offenders (those who have shown a capacity for violence either in the past or in the current offense). The third alternative would implement a program of geriatric release in California prisons.
