Evaluating Firearm Violence After New Jersey's Cash Bail Reform

Area of Science:

• Public Health
• Criminology
• Health Equity

Background:

• Reducing pretrial detention is key to ending mass incarceration.
• Debates exist on bail reform's impact on community violence.
• Racial and economic disparities are linked to incarceration and gun violence.

Purpose of the Study:

• To evaluate the impact of New Jersey's 2017 bail reform on firearm violence.
• To determine if eliminating financial barriers to pretrial release affects community safety.

Main Methods:

• Case-control study using synthetic control methods (2014-2019).
• Compared New Jersey firearm violence rates with 36 non-reform states.
• Analyzed quarterly rates of fatal/nonfatal firearm injuries per 100,000 people.

Main Results:

• New Jersey's pretrial detention population significantly decreased post-reform.
• No evidence of increased overall firearm mortality (ATE -0.26/100,000).
• No evidence of increased gun violence (ATE -0.24/100,000) or within racialized groups.

Conclusions:

• Bail reform can reduce pretrial detention without increasing community gun violence.
• Cash bail reform may be a tool for advancing health equity.
• Policy changes can address public health issues linked to incarceration and violence.
