Front & Center #1:  Abolishing Cash Bail in Illinois--What You Missed

Professors Don Stemen and David Olson of Loyola University Chicago CCJ examine whether crime has increased in places that have implemented bail reforms since 2017.

Is Bail Reform Causing an Increase in Crime?

We explore how important monetary bail is as a source of restitution for victims of crime and whether the elimination of monetary bail will have the unintended consequence of reducing compensation for victims.

Will Eliminating Monetary Bail Deprive Crime Victims of Compensation?

Practitioner interviews suggest that bail is imposed for a broader range of purposes than is usually articulated, at least in public. Our analyses of available data show that bail’s practical results are different from those that are widely assumed. And our conversations with defendants—people who know the pretrial system from inside—have surfaced beliefs and perceptions about bail that are both disturbing and important.

Paying in Advance: Perceptions of Monetary Bail in Illinois

The Center collaborated with the Illinois Department of Corrections’ Planning and Research Unit to examine the number, characteristics, and circumstances of individuals on Mandatory Supervised Release (MSR, or “parole”) who violated conditions of their release and were returned to prison (i.e., “technical violators”).
