Key Evidence
Multiple reputable sources including the Brennan Center for Justice and the American Civil Liberties Union find no evidence that bail reform causes increased crime; increases in violent crime during recent years are attributed to broader societal factors including the pandemic.

What the Evidence Shows
The claim asserts a direct and significant rise in crime coinciding with the adoption of cashless bail in American cities. Breaking down the claim, it involves two key components: first, that crime rates have risen significantly, and second, that this rise is causally linked to the implementation of cashless bail. Evidence shows that violent crime did increase in many U.S. Cities during recent years, particularly amid the COVID-19 pandemic.brennancenter.orgbrennancenter.orgThe Facts on Bail Reform and Crime Rates in New York State
However, multiple authoritative analyses and research reports find no conclusive causal link between bail reform, including cashless bail, and increases in crime rates. For example, the Brennan Center for Justice states that available data does not support the idea that bail reform drives crime increases. Some studies even suggest that pretrial incarceration associated with cash bail can increase recidivism.brennancenter.orgbrennancenter.orgDebunking Myths About Bail Reform and Crime
The claim oversimplifies a complex issue by implying direct causation without accounting for confounding factors such as pandemic-related social disruptions, economic stressors, policing changes, and other criminal justice reforms. While some critics argue that bail reform may contribute to repeat offenses by certain individuals,americanprogress.orgamericanprogress.orgCash Bail Reform Is Not a Threat to Public Safety this is not equivalent to a broad, significant rise in overall crime caused by cashless bail policies.
The temporal correlation between bail reform and crime trends does not establish causation, and the evidence base does not support the claim as stated. Therefore, the claim is mostly false because it misrepresents the relationship between bail reform and crime rates.
