Key Takeaways
- 4.4 million stops occurred between 2003 and 2013, meaning stop-and-frisk was used on a multi-million scale over roughly a decade.
- Stop-and-frisk was suspended by NYPD in 2020 as part of policy changes following court and settlement reforms, meaning the core practice was effectively curtailed.
- In the NYPD’s own Frisk Yield analysis, the ‘hit rate’ for frisks was about 10% (contraband found), meaning only about 1 in 10 frisks produced a hit on average.
- In Floyd v. City of New York, the court found that the NYPD frequently lacked reasonable suspicion to justify stops, meaning many stops were not supported by the legal standard.
- The federal court held that officers’ stops were often not supported by reasonable suspicion, meaning constitutional thresholds were frequently unmet.
- A 2018 JAMA Internal Medicine study reported that exposure to stop-and-frisk was associated with increased likelihood of depressive symptoms among youth, meaning policing practices had measurable mental health harms.
- A 2019 study published in the Proceedings of the National Academy of Sciences found stop-and-frisk policies affected public health and well-being, meaning enforcement practices had broader societal impacts than arrest statistics alone.
- A 2017 RAND report found that legal and community legitimacy are critical to policing effectiveness, suggesting stop-and-frisk’s disproportionate burden can undermine legitimacy, meaning perceived fairness can affect cooperation.
- A 2017 study in Social Science & Medicine reported that police-stop exposure is associated with adverse mental health outcomes, implying potential downstream healthcare costs, though not directly quantified as dollars in that paper.
- A 2019 report by the Office of the New York State Comptroller indicated that legal compliance and oversight for consent decrees can require continuing administrative spending, meaning public-sector compliance carries ongoing costs.
- $2.6 million: annual training and compliance staffing costs for officers and supervisors under documented policing reform implementation plans.
- Alabama statute: “Reasonable suspicion” standard remains the constitutional baseline for stop-and-frisk-type investigatory detentions under the Fourth Amendment and relevant state codifications (quantified in case law applications).
- 27% of youth in a cohort reported at least one stop exposure (self-reported) over a multi-year period, linking exposure prevalence to youth policing experiences.
- 14% higher odds of depressive symptoms among youth exposed to stop-and-frisk in a longitudinal analysis (adjusted odds ratio reported in the study).
- 4.0% decrease in self-reported trust in police after stop exposure in a panel study of policing experiences, reported as a marginal difference in trust scores.
From 2003 to 2013, millions of stops yielded only about a 10 percent contraband hit rate.
