A celebrated Seattle criminal justice diversion initiative once hailed as a national model is now under fire after a new analysis alleges that its touted success in reducing crime and transforming lives was grossly overstated, and that participants were far more likely to die than to find work.
According to The Post Millennial, the Law Enforcement Assisted Diversion (LEAD) program, launched in Seattle and replicated in jurisdictions across the country, was long promoted as a breakthrough in harm reduction and progressive criminal justice reform. For more than a decade, policymakers were told that LEAD participants were 58 percent less likely to be arrested, that felony charges dropped by 39 percent, and that employment and housing outcomes improved dramatically for those enrolled in the program.
Those claims helped fuel a wave of legislative endorsements, budget allocations, and grant awards in more than 20 states, embedding LEAD into the broader national push to move offenders away from traditional prosecution and incarceration and into social-service-based alternatives.
A new national review, however, contends that the reality behind those numbers is far less impressive and, in some respects, deeply troubling. The August 2026 National Retraction Brief, authored by Washington Policy Center Public Safety Solutions Policy Director Eric Zimmerman, asserts that LEADs foundational research was repeatedly misrepresented as the program spread nationwide, distorting the evidence base that lawmakers and local officials relied upon.
Zimmermans report focuses heavily on employment outcomes, a key measure of whether participants are actually turning their lives around rather than simply avoiding jail. Among 176 LEAD participants examined for employment outcomes, 91 percent remained unemployed on average, a figure that stands in stark contrast to federal data on ex-offenders. The report juxtaposes those results with 2019 Bureau of Labor Statistics (BLS) research tracking men after release from at least six months of incarceration, noting that 33.9 percent were employed within one week of release, and 50.3 percent were employed by week ten.
The comparison suggests that individuals leaving traditional incarceration may have fared better in the labor market than those routed into Seattles flagship diversion program. According to the report, three times as many LEAD participants died as the estimated number who gained employment during the study period, a grim statistic that raises serious questions about whether the program is truly serving as a path to stability or merely warehousing addiction and homelessness under a different label.
Housing outcomes, another central selling point for LEAD, also appear far weaker than the programs promotional materials have implied. LEAD research has been widely advertised with claims that participants odds of being housed increased 89% or that participants were 89% more likely to obtain permanent housing during the follow-up. Yet Zimmermans analysis of the underlying data finds that of 146 participants who were unhoused when they entered LEAD, an estimated average of only 19 were permanently housed in a given month during the 18?month follow-up period, equivalent to approximately 13 percent of those entering without permanent housing.
Shelter placement performed somewhat better, but still fell short of the sweeping rhetoric used to justify the programs expansion. The report notes that an estimated average of 31 participants appeared to be sheltered in a given month, and even when shelter and permanent housing are combined, LEAD achieved only a 35 percent success rate in connecting initially unhoused participants with either shelter or permanent housing. For a program marketed as a transformative solution to chronic homelessness and street disorder, those numbers suggest modest gains at best.
Zimmerman also highlights a major methodological limitation in the housing portion of the LEAD study: the absence of a control group. Without a comparable group of non-participants, it is difficult to determine whether observed housing changes are attributable to LEAD or to broader trends in the local housing system. To approximate a comparison, the report looks to federal housing data from King County over roughly the same period, noting that the countys sheltered-homelessness rate declined slightly, from 70.5 percent in 2012 to 69.4 percent in 2014.
Despite these limitations, Zimmerman concedes that connecting participants to shelter and housing may represent LEADs most plausible treatment effect beyond reducing contact with the criminal justice system. He argues that the program could potentially be more accurately understood as a point-of-arrest intake mechanism for Housing First programs rather than as a robust crime-reduction strategy. Even on this narrower measure, however, the report underscores that the number of participants who died was approximately half the estimated number entering permanent housing during the study period, underscoring the severe vulnerabilities of the population LEAD serves and the limited protective effect the program appears to provide.
The most politically potent claims surrounding LEAD have centered on arrests and felony charges, which were repeatedly cited by advocates as proof that the program reduces crime. Despite the abysmal real-world outcomes documented in the report, LEAD was promoted locally and nationally using dramatically different numbers, including the assertion that participants were 58% less likely to be arrested. Zimmermans report contends that researchers reported an odds ratio that was subsequently promoted as a 58 percent reduction in arrests, crime, or recidivism, a statistical sleight of hand that transformed a technical measure into a sweeping public-relations talking point.
The report identifies similar problems with claims that LEAD reduced felony charges by 39 percent and improved employment outcomes by 46 percent. According to Zimmerman, promoters of the program repeatedly confused or conflated key mathematical concepts, including odds versus probability and absolute versus relative change, thereby inflating the apparent impact of the intervention. For arrests, the report identifies an unadjusted 22?percentage?point difference between LEAD participants and the control group after entry, but Zimmerman cautions that even that difference cannot reliably be attributed to LEAD because the groups experienced different recruitment practices, policing patterns, timelines, and geographic conditions.
Moreover, LEAD participants appear to have benefited from reductions or dismissals of charges that affected subsequent warrant arrests in ways the control group did not. According to the report, the King County Prosecuting Attorneys Office was an unblinded operational partner, and prosecutors could take LEAD participation and progress into account when determining whether and when to file felony charges. This arrangement, Zimmerman argues, means that the 11?percentage?point unadjusted difference in felony rates cannot be cleanly attributed to LEAD changing participants criminal behavior, because the justice system itself treated LEAD participants differently from similarly situated offenders.
Despite these methodological and ethical concerns, LEAD expanded far beyond Washington after its Seattle launch, riding a wave of enthusiasm for evidence-based alternatives to incarceration. Santa Fe, New Mexico, became one of the earliest jurisdictions to replicate the model, followed by Albany, New York, and Fayetteville, North Carolina, as progressive prosecutors and city leaders embraced diversion as a humane and cost-effective response to low-level crime. LEAD programs or pilots were subsequently established in major urban centers and smaller communities alike, including Los Angeles and San Francisco, California; Baltimore, Maryland; Washington, DC; Portland, Oregon; Huntington and Charleston, West Virginia; and jurisdictions in New Jersey and Maine.
North Carolina has continued expanding the model even as questions about its evidence base mount. The state announced $1.5 million in funding in March 2026 for LEAD programs involving Fayetteville, Albemarle, and Greensboro, as well as the counties of Gaston, New Hanover, Robeson, and Harnett, signaling that the program remains politically attractive despite the emerging doubts. For conservatives wary of soft-on-crime policies, the continued investment in a program now alleged to have overstated its success will likely reinforce concerns that ideological commitments, rather than hard data, are driving criminal justice policy.
Zimmermans report emphasizes that the disputed statistics originating with Seattles program did not remain local curiosities but became embedded in the national narrative surrounding LEAD. As the diversion model developed into a widely replicated template, versions of the contested claims appeared in materials from police departments, universities, prosecutors, state governments, medical and criminal justice publications, and organizations promoting LEAD. The report documents versions of the 58 percent claim appearing in sources including the Seattle Police Department, University of Washington, LEAD Seattle/King County, Duke Law School, Michigan State Police, New Mexico State Legislature, National Association of Counties, American Journal of Public Health, and King County Prosecuting Attorneys Office.
Other sources went even further, describing the finding more broadly as LEAD participants having 58 percent fewer arrests, recidivism, or crime, according to the report. Those sources included an American Journal of Criminal Justice article, New York State Department of Health materials, and organizations in Maryland and North Carolina, illustrating how a single misinterpreted statistic can cascade through academic, governmental, and advocacy networks. The report traces the statistical problem back to the initial promotion of LEAD research in 2015, including press releases from the Seattle Police Department and University of Washington, saying a finding concerning the odds of arrest was subsequently translated into claims about probability and absolute percentage changes.
The result, Zimmerman argues, was that policymakers around the country were making decisions about an allegedly evidence-based criminal justice program using statistics that substantially exaggerated what the underlying research could prove. The report says those differences could have been material to legislative votes, government appropriations, and competitive grants, where stronger claims of program performance could affect funding decisions and crowd out more effective alternatives. For those who favor a more traditional law-and-order approach, the episode underscores the danger of allowing activist-driven narratives and flawed social science to supplant common-sense enforcement and accountability.
Claims originating from one flawed Seattle study became part of the evidence used to promote the model far beyond Washington, shaping policy debates in some of the nations most influential states. When California lawmakers considered legislation establishing LEAD pilot programs, a legislative analysis cited the Seattle evaluation as finding that participants were 58% less likely to be arrested than members of the control group, a framing that likely reassured legislators that they were backing a proven reform. California subsequently authorized LEAD pilots, including programs in Los Angeles and San Francisco, cities already grappling with rising disorder and public frustration over lenient criminal justice policies.
Albany, New York, which launched LEAD in 2016, has similarly cited Seattles results while operating its own version of the diversion model. In North Carolina, Fayetteville launched an early program, and the state has continued putting public money behind expansion of the model, even as Zimmermans findings call its core claims into question. Versions of the disputed Seattle statistics appeared in North Carolina government and policy materials describing LEADs evidence base, suggesting that state officials may have been relying on overstated or mischaracterized data when deciding how to allocate scarce public safety resources.
In light of these concerns, Zimmerman is now calling for governments already operating LEAD to pause expansion and submit the programs to independent external audits. The report recommends that policymakers evaluate alternatives on a case-by-case basis, including baseline criminal justice responses and diversion tied to compliance or residential treatment, rather than defaulting to a single model that may not deliver on its promises. It also advocates increased investment in rehabilitative jail programs and post-release support, including vocational education, financial literacy, life-skills training, and community, peer, and accountability-based support, approaches more consistent with a conservative emphasis on personal responsibility and structured rehabilitation.
For drug offenses, the report recommends strengthening frameworks that increase the certainty of arrest, prosecution, and incarceration while simultaneously offering compliance-based avenues for reduced sentences, early release, or intermittent confinement. This model seeks to balance firm enforcement with genuine opportunities for redemption, rather than offering unconditional leniency that may enable continued criminal behavior and addiction. Jurisdictions currently considering LEAD, meanwhile, should suspend adoption until rigorous evidence demonstrating real-world participant outcomes is available, according to the report, a call that aligns with demands for fiscal prudence and evidence-driven governance.
Zimmerman also calls for published scholarship that inadvertently repeated inaccurate descriptions of LEAD research to annotate those claims. The report argues that LEAD and other diversion programs should establish measurable goals and publicly report whether participants are actually improving, rather than relying on abstract rhetoric about harm reduction or restorative justice. The recommended metrics include participant mortality, loss to follow-up, reductions in drug use, abstinence, employment, income growth, housing independence, and longevity in permanent supportive housing, benchmarks that would allow citizens and lawmakers alike to judge whether these programs are genuinely promoting safety and recovery or merely shifting problems out of sight.
