The Defense Technology Gap: How Prosecution Outspends Defense 10:1 on Forensic Tools

The criminal justice system is built on the premise of equal adversarial advocacy, yet a growing technology gap threatens to undermine this foundation. This research report presents original data from over 500 public defender offices and 200 prosecution agencies, revealing that prosecution spending on forensic analysis tools outpaces defense spending by a ratio of more than ten to one.

Our analysis examines the downstream effects of this disparity on case outcomes, plea bargaining dynamics, and wrongful conviction rates. We find that jurisdictions with the largest technology gaps also show the highest rates of overturned convictions on appeal, suggesting that forensic tool access is not merely a convenience but a constitutional concern.

The report concludes with actionable policy recommendations for legislatures, bar associations, and technology providers to close this gap, including grant programs, shared-resource models, and open-source forensic tool initiatives that could level the playing field without requiring massive new public expenditure.
