Parole in Perspective: A deep dive into discretionary parole systems
Parole, a release mechanism that could significantly reduce the number of people behind bars, has reached a moment of reckoning. Dysfunctional in some states and banned in others, parole looks very different from state to state. But parole is a system worth having, if states can implement it fairly and broadly.
In this two-part report, Parole in Perspective, we take a deep dive into these systems, providing the most accessible and comprehensive look at how they operate, and what can be done to make them real tools for decarceration.
- In part 1, we examine the composition of these boards and how their hearings work.
- In part 2, we look at parole grant rates and the decisionmaking guidelines and realities that lead to those rates.
