Pretrial Release Impact
Did pretrial release rates change differently for the types of cases targeted by New York's May 2022 and June 2023 bail-law amendments? This branch analyzes 854,000 cases from the DCJS/OCA supplemental pretrial release file (2021–2024).
Key Findings
May 2022 Amendment
Firearm charges newly eligible for detention saw the sharpest shift. Release rates dropped 20 pp (NYC) to 32 pp (non-NYC) more than baseline.
Note: The firearm group is small (186 cases statewide). Repeat harm/theft cases (~164K) show a more modest 3.7 pp drop.
June 2023 Amendment
The repeat offender group (~164K cases) shows smaller shifts. NYC: <1 pp difference from baseline. Non-NYC: ~2.5 pp.
Note: This amendment had a narrower scope. The observed changes are modest and within the range of normal variation.
Release-Rate Changes by Exposure Group
Difference-in-DifferencesEach bar shows how much the exposed group's release rate changed relative to the comparison group across the amendment window. Negative values mean the exposed group's release rate dropped more than the comparison.
May 2022 Amendment: Diff vs. Comparison
Exposed group change minus comparison group change (release rate, pp)
June 2023 Amendment: Diff vs. Comparison
Exposed group change minus comparison group change (release rate, pp)

Important Caveats
Observational design: This is a before-after comparison, not a controlled experiment.
Other policy changes, judicial turnover, or caseload shifts could contribute to the observed changes.
Small samples: The firearm charge groups are very small (dozens of cases), making
point estimates unstable. The large percentage-point changes should be interpreted cautiously.
Proxy definitions: Exposure groups are defined by charge-type proxies that approximate
but do not perfectly match the statutory categories targeted by each amendment.
No causal claim: The analysis describes whether release rates changed differently for
targeted vs. non-targeted charges. It does not establish that the amendments caused the changes.
