Peter Neufeld

Peter J. Neufeld is an American civil rights attorney renowned for his work on wrongful convictions and forensic science reform, most notably as co-founder and special counsel of the Innocence Project, established in 1992 at the Benjamin N. Cardozo School of Law with Barry Scheck.^[1]^[2] The Innocence Project employs post-conviction DNA testing to exonerate factually innocent individuals, having contributed to the release of over 375 such prisoners nationwide through empirical validation of innocence via genetic evidence, while systematically documenting causal factors in miscarriages of justice including erroneous eyewitness identifications, false confessions, and unreliable traditional forensic methods like serology and microscopy.^[3]^[4] Neufeld's litigation career includes high-profile defenses against police misconduct and his role as a forensic DNA expert on the O. J. Simpson defense team in 1995, where he challenged prosecution evidence interpretations.^[5] He has taught trial advocacy and directed clinical programs at institutions such as Fordham University School of Law and Cardozo, and served on the National Commission on Forensic Science to address deficiencies in forensic validation.^[6]^[7] Co-author of the influential book Actual Innocence (2000), Neufeld's efforts underscore the empirical limitations of non-DNA forensics, as demonstrated by DNA exonerations revealing error rates exceeding 60% in certain disciplines like bite mark analysis.^[8]^[9]

Early life and education

Childhood and family background

Peter Neufeld was born on July 17, 1950, in New York City.^[10] He spent much of his formative years in West Hempstead on Long Island, attending local schools including West Hempstead High School, from which he graduated.^[11] Publicly available details on Neufeld's immediate family and household dynamics during childhood remain sparse, with no documented accounts of parental occupations, siblings, or specific early-life events that directly shaped his worldview. His upbringing in a suburban Long Island community during the post-World War II era provided a stable environment amid broader national shifts, though personal anecdotes linking family influences to later interests in justice remain undocumented in accessible biographical records.^[11]

Academic training and early influences

Neufeld earned a Bachelor of Arts degree from the University of Wisconsin-Madison in 1972.^[12] He subsequently attended New York University School of Law, where he obtained his Juris Doctor in 1975.^[12]^[13] These academic pursuits introduced Neufeld to core principles of criminal law, evidence evaluation, and analytical reasoning, establishing a basis for his eventual scrutiny of forensic methodologies.^[14] The mid-1970s legal education environment at NYU, amid broader shifts in criminal defense toward challenging prosecutorial evidence in civil rights contexts, cultivated an early emphasis on rigorous validation of testimonial and scientific claims in litigation.^[6]

Legal career

Public defender years and initial litigation

Neufeld began his legal career as a staff attorney at the Legal Aid Society in the Bronx, New York, in the mid-1970s, following his receipt of a J.D. from New York University School of Law in 1975.^[12] He remained in this role through the mid-1980s, representing indigent defendants in routine criminal cases amid a high-volume caseload typical of the Bronx public defense system.^[15] During this period, Neufeld's practice centered on exposing vulnerabilities in prosecutorial evidence, particularly the unreliability of eyewitness identifications, which empirical studies have shown contribute to a significant portion of wrongful convictions, and preliminary flaws in forensic analyses predating widespread DNA adoption.^[16] In these defenses, Neufeld frequently litigated claims of police misconduct, including allegations of evidence tampering or coercive interrogation tactics that undermined fair trials.^[4] His approach involved rigorous cross-examination of witnesses and motions to suppress tainted physical evidence, yielding occasional appellate successes where courts identified procedural errors leading to conviction reversals. This hands-on experience with evidentiary weaknesses built his expertise in contesting overreliance on human perception and unverified scientific claims in court.^[5] Neufeld's tenure also overlapped with his meeting Barry Scheck, another Legal Aid attorney, fostering early discussions on systemic issues in criminal adjudication.^[15] By the early 1980s, while continuing public defense work, Neufeld taught trial advocacy at Fordham University School of Law, refining strategies that prioritized data-driven dissection of testimony over traditional narrative persuasion.^[5] These methods emphasized falsifiability and reproducibility in evaluating prosecution claims, laying a tactical foundation for later challenges to forensic orthodoxy without invoking post-conviction DNA applications.

Private practice and pre-Innocence Project cases

Following his seven years as a public defender with the Legal Aid Society's Criminal Defense Division in the South Bronx, starting in 1975, Neufeld transitioned to private practice in the mid-1980s.^[17] During this period, he also served as Director of Clinical Education at Benjamin N. Cardozo School of Law from 1978 to approximately 1988, where he supervised high-profile criminal cases handled by students, gaining deeper insights into evidentiary flaws common in prosecutions.^[17] In private practice, Neufeld specialized in civil rights litigation under Section 1983, targeting law enforcement agencies for constitutional violations, including wrongful arrests based on coerced confessions, unreliable eyewitness identifications, and deficient probable cause.^[4] These suits sought damages for victims of police misconduct and aimed to expose systemic failures in investigation and detention practices that led to erroneous detentions and convictions, distinct from routine criminal defense by emphasizing accountability and reform through monetary penalties and policy scrutiny.^[4] His work highlighted patterns of error, such as overreliance on unverified confessions obtained through suggestive interrogation tactics, which empirical reviews later confirmed as a leading cause of wrongful outcomes in non-DNA exonerations.^[5] Neufeld's early collaborations with Barry Scheck, dating to their Legal Aid days in the 1970s and intensifying in the 1980s, focused on dissecting forensic reliability in civil rights contexts, including critiques of traditional techniques like microscopic hair comparison, which lacked empirical validation and contributed to misidentifications in arrest justifications.^[5] Without formal organizations, their joint efforts in these pre-1992 cases built a foundational understanding of conviction vulnerabilities, informing subsequent advocacy while prioritizing case-specific challenges to flawed evidence admissibility and investigative integrity.^[5]

Role in the O.J. Simpson defense

Peter Neufeld served as a forensic DNA expert on O. J. Simpson's defense team during the 1994-1995 murder trial, alongside Barry Scheck, focusing on challenging the prosecution's DNA evidence from blood samples collected at the crime scene, Simpson's Ford Bronco, and his property.^[18]^[19] Neufeld cross-examined laboratory directors, including Robin Cotton of Cellmark Diagnostics, to highlight risks of contamination during sample collection and processing by the Los Angeles Police Department, emphasizing that EDTA preservative from reference vials could indicate tampering or cross-contamination rather than incidental transfer.^[18]^[20] He argued against the admissibility and reliability of the DNA matches by pointing to documented laboratory error rates, such as proficiency test failures at Cellmark where critics calculated an error rate as high as 2% based on validation studies involving mixed samples, and by critiquing the prosecution's statistical interpretations of genetic frequencies in blood mixtures.^[18]^[21] Neufeld also exposed chain-of-custody breaches, including unlogged handling of evidence by LAPD technicians and failure to document protocols, which undermined the prosecution's claims of sample integrity under early 1990s forensic standards prone to human error without modern safeguards like blind testing.^[22]^[23] These challenges created reasonable doubt among jurors regarding the DNA evidence's probative value, contributing to Simpson's acquittal on October 3, 1995, as the defense portrayed the matches not as definitive proof but as susceptible to artifacts from sloppy procedure rather than causation by guilt.^[24] In post-trial commentary, Neufeld reflected that the case demonstrated DNA's dual-edged nature: a powerful identifier when protocols are rigorous, yet prone to miscarriages when error rates from contamination or mishandling—evidenced by pre-trial lab audits showing false positives—override empirical validity, influencing subsequent scrutiny of forensic practices.^[25]

Establishment and leadership of the Innocence Project

Peter Neufeld and Barry Scheck co-founded the Innocence Project in 1992 as a legal clinic at the Benjamin N. Cardozo School of Law at Yeshiva University, focusing on post-conviction DNA testing to review cases of potentially wrongfully convicted prisoners.^[26] The clinic was established to systematically apply emerging DNA technology to biological evidence from archived cases, aiming to exonerate the innocent while identifying causes of miscarriages of justice.^[2] Neufeld, drawing from his experience in challenging flawed forensic evidence, co-directed operations alongside Scheck, initially handling a limited caseload with volunteer law students.^[6] Under Neufeld's leadership as co-director, the Innocence Project grew from a modest clinic with two staff members to a national nonprofit organization by the early 2000s, receiving thousands of applications yearly from inmates seeking DNA review.^[1] Neufeld oversaw strategic litigation, prioritizing cases with testable biological evidence, and shaped policy initiatives to address systemic flaws in the criminal justice process. This expansion included building partnerships with forensic labs and advocating for improved standards in evidence handling, transforming the project into a leading voice on wrongful convictions.^[26] The organization's work emphasized empirical patterns in reviewed cases, revealing eyewitness misidentification as a contributing factor in over 70% of DNA-based exonerations, alongside issues like unreliable forensics and false confessions.^[27] Neufeld directed efforts to catalog these trends, using data from hundreds of investigations to inform operational priorities and broader reforms, without litigating every claim but focusing on those demonstrating clear evidentiary potential.^[2] This analytical framework distinguished the Innocence Project, enabling targeted resource allocation amid overwhelming demand.^[28]

Teaching, speaking, and advisory roles

Neufeld taught trial advocacy as an adjunct professor at Fordham University School of Law from 1988 to 1991, emphasizing practical litigation skills for future attorneys.^[8] ^[14] Since the mid-1990s, he has instructed students at the Benjamin N. Cardozo School of Law through the Innocence Project clinic, where participants analyze post-conviction claims involving potential wrongful convictions and develop strategies for DNA testing and evidentiary challenges.^[29] ^[30] Neufeld has delivered keynote addresses at forensic and justice-focused events, including the 2022 Benefit for Innocence conference on "The Science of Justice," where he addressed advancements in DNA evidence and systemic reforms.^[31] ^[32] He has also spoken at academic gatherings, such as the 2019 Center for Statistics and Applications in Forensic Evidence (CSAFE) conference at Duke Law School, discussing error rates in forensic identification methods.^[33] In advisory capacities, Neufeld served as a commissioner on the National Commission on Forensic Science from 2014 to 2017, contributing to federal recommendations on validating forensic techniques and accrediting laboratories to enhance reliability in criminal proceedings.^[29] ^[34] He has held appointments to the New York State Commission on Forensic Science by four successive governors, overseeing regulation of the state's crime laboratories and standards for evidence handling.^[14] These roles focused on policy-level improvements to forensic protocols without direct involvement in individual cases.^[35]

Advocacy on forensic evidence

Pioneering use of DNA for exonerations

In the late 1980s, Peter Neufeld and Barry Scheck initiated litigation to apply emerging DNA testing technologies to challenge convictions, focusing on cases where biological evidence could definitively exclude suspects through genetic profile mismatches.^[1] Their work began with admissibility challenges to ensure rigorous laboratory standards, establishing protocols that leveraged DNA's empirical reliability—typically achieving exclusion certainty and match probabilities better than 1 in 10 billion for unrelated individuals when using short tandem repeat (STR) analysis. This approach succeeded causally by providing objective, quantifiable evidence that bypassed interpretive biases in traditional identification methods, such as serological comparisons reliant on subjective pattern assessment.^[36] A pivotal early example was their defense of Marion Coakley, convicted in 1985 of rape; in 1989, DNA testing they advocated excluded Coakley as the source of semen evidence, marking one of the first instances of post-conviction DNA analysis revealing factual innocence despite eyewitness and forensic testimony supporting guilt.^[36] Although Coakley's case did not immediately lead to exoneration due to prosecutorial resistance, it underscored DNA's capacity for re-testing archived evidence in closed cases, prompting Neufeld and Scheck to develop legal strategies for overcoming barriers like evidence degradation and statutes of limitations.^[5] By the early 1990s, their persistent court filings expanded access to such testing, directly influencing the framework for subsequent exonerations.^[37] Neufeld's advocacy emphasized DNA's first-principles validation: its binary exclusion outcome (match or no match) combined with low random match probabilities ensured causal linkage to innocence claims, independent of confirmatory biases in original trials.^[15] This methodological innovation, refined through 1980s-1990s precedents, positioned DNA as a cornerstone for post-conviction relief, distinct from its prosecutorial origins.^[2]

Critiques of traditional forensic techniques

Peter Neufeld has extensively critiqued non-DNA forensic disciplines, particularly those reliant on subjective pattern matching, such as microscopic hair comparison and bite-mark analysis, arguing that they lack empirical validation and contribute to wrongful convictions through overstated certainty in expert testimony. In a 2009 study co-authored with Brandon Garrett, Neufeld analyzed forensic testimony in the trials of 137 defendants later exonerated by DNA evidence, finding that flawed non-DNA evidence, including hair analysis, was presented in 34% of cases, often with claims of "microscopic similarity" implying virtual certainty despite no statistical foundation for such assertions.^[38] This work underscored how examiners frequently exceeded the limits of their methods, testifying to matches that DNA later contradicted, highlighting a systemic failure to quantify error rates or probabilities. Neufeld's critiques gained prominence through his involvement in the 2009 National Research Council (NRC) report, Strengthening Forensic Science in the United States: A Path Forward, which he influenced via prior advocacy and testimony; the report concluded that fields like hair and bite-mark analysis rested on "little rigorous, objective research on the reliability" of their foundational validity, lacking black-box studies to measure false positives and advocating replacement of subjective certainty with probabilistic assessments.^[39] In Senate testimony that year, Neufeld cited cases like Ray Krone's, where unvalidated bite-mark evidence led to conviction, later disproven by DNA, labeling such techniques as prone to "disturbingly low" accuracy due to variability in human interpretation and absence of standardized error metrics. A pivotal data point in Neufeld's arguments emerged from a 2015 FBI review of its own microscopic hair cases, revealing errors in analysts' testimony in over 90% of sampled trials, where phrases like "consistent with" were inflated to near-certain identifications without empirical support, contributing to at least 35 death-row convictions among hundreds affected.^[40] He has pushed for rigorous validation akin to DNA testing, including controlled proficiency tests showing inter-examiner disagreement rates exceeding 20% in hair comparisons, to supplant anecdotal experience with falsifiable standards. Opposing views from forensic practitioners and law enforcement maintain that these techniques retain investigative value when not presented as infallible, attributing errors primarily to testimonial overreach rather than inherent invalidity, and arguing that experiential expertise—honed over thousands of cases—provides probabilistic insights unavailable through lab validation alone, though such defenses have not produced population-based error rate studies to counter Neufeld's demands.^[41]

Contributions to scientific validation standards

Neufeld co-authored a 2009 empirical study with Brandon Garrett examining forensic expert testimony in 137 trials resulting in wrongful convictions later exonerated by post-conviction DNA testing, finding that examiners routinely overstated the certainty of matches in non-DNA disciplines such as microscopic hair comparison (60% of cases), bite mark analysis (all sampled cases), and toolmark identification, often asserting "practical impossibility" or infinitesimal probabilities without supporting error rate data from controlled studies.^[42] The analysis demonstrated that such claims deviated from scientific norms by lacking peer-reviewed validation of foundational premises, including reproducibility and false positive quantification, and recommended mandatory black-box proficiency testing and population-based databases to establish empirical error rates.^[42] This work underscored causal gaps in traditional forensic methodologies, where subjective pattern matching failed to distinguish source-level attributions from class-level similarities absent rigorous experimentation. Through congressional testimony, Neufeld urged the establishment of independent, ongoing scientific oversight for forensic practices, advocating in 2009 for validation protocols mirroring DNA standards—encompassing method reliability, analyst proficiency, and laboratory accreditation—to mitigate cognitive biases and ensure admissibility under evidentiary rules like Daubert.^[43] His 2012 testimony reiterated calls for federal funding of peer-reviewed research into non-DNA techniques, emphasizing that without systematic error characterization, courts risk admitting evidence prone to overinterpretation.^[44] These positions informed broader reforms, including the 2016 PCAST report, which Neufeld supported and which critiqued fields like firearms and toolmark examination for insufficient foundational validity studies, proposing instead probabilistic reporting via likelihood ratios derived from Bayesian frameworks to reflect actual match specificity rather than anecdotal certainty claims.^[35]^[45] Neufeld has contributed to amicus curiae briefs challenging unvalidated techniques, such as a filing asserting that hair microscopy evidence requires empirical peer review to substantiate claims of individuality, absent which it constitutes unreliable opinion testimony.^[46] His advocacy has promoted standardization through bodies like the National Institute of Standards and Technology, prioritizing causal realism by linking evidentiary conclusions to verifiable mechanisms of error reduction over legacy practices. While these standards have enhanced empirical grounding in select disciplines, prosecutors and some forensic practitioners argue that demands for extensive validation data can exclude probative evidence in resource-constrained labs, potentially prolonging investigations without commensurate gains in accuracy.^[47] Neufeld counters that incomplete validation perpetuates systemic unreliability, as evidenced by historical exonerations tied to untested methods.^[42]

Impact and debates

Exonerations facilitated and systemic effects

Under Neufeld's co-leadership of the Innocence Project, the organization has facilitated the exoneration of 204 clients through post-conviction DNA testing as of September 2025, contributing to broader documentation of over 375 DNA exonerations nationwide since 1989.^[3] These cases involved individuals who collectively served more than 4,000 years in prison prior to release, with an average of 16 years incarcerated per exoneree.^[3] DNA evidence in these instances directly contradicted prior convictions, often by excluding the defendant as the source of biological material or identifying alternative perpetrators.^[48] Patterns in these exonerations reveal recurring causal factors in the original wrongful convictions. Eyewitness misidentification appeared in approximately 70% of DNA exoneration cases tracked by the Innocence Project, frequently involving cross-racial identifications or suggestive lineup procedures that undermined reliability.^[27] Official misconduct, such as withholding exculpatory evidence or improper prosecutorial arguments, factored into over 40% of cases, directly enabling flawed convictions that DNA later overturned.^[49] These elements, combined with issues like false confessions in about 25% of DNA cases, illustrate how interdependent errors in identification, investigation, and prosecution sustained imprisonment until genetic testing provided irrefutable reversal.^[48] Beyond strictly DNA-driven outcomes, Neufeld's involvement extended to non-DNA exonerations demonstrating the Innocence Project's influence on systemic case reviews. In the Central Park Five case, the organization supported the 2002 exoneration of five teenagers convicted of a 1989 assault and rape, where initial DNA exclusion of the defendants was ignored, and a serial rapist's later confession aligned with the evidence; Neufeld publicly affirmed the vindication as comprehensive following their 2002 release and settlement.^[50] This effort highlighted applicability to pre-DNA era convictions reliant on confessions and eyewitness accounts, broadening the project's role in rectifying miscarriages through evidentiary reexamination.^[51]

Policy reforms and institutional changes

Neufeld's work with the Innocence Project helped drive federal legislation expanding access to post-conviction DNA testing, including advocacy that informed the Innocence Protection Act provisions within the Justice for All Act of 2004, which required the preservation of biological evidence in federal cases where charges resulted in death sentences and authorized grants for improving state-level DNA testing capabilities.^[52] This built on state-level reforms in the 1990s and early 2000s, where Innocence Project efforts prompted over 40 states to enact laws broadening post-conviction DNA access by 2009, facilitating re-testing of evidence in thousands of cases.^[52] Neufeld testified before congressional committees on forensic reliability, contributing to the 2009 National Research Council report Strengthening Forensic Science in the United States: A Path Forward, which identified foundational flaws in non-DNA forensic methods like hair and bite-mark analysis and recommended establishing an independent oversight body for standards, accreditation, and research funding.^[53]^[39] In response, the Department of Justice launched the National Commission on Forensic Science in 2014, comprising scientists, practitioners, and advocates, which issued uniform protocols for trace evidence handling and validation by 2016, influencing over 20 work products adopted by federal agencies.^[54] Building on the NRC findings, Neufeld's ongoing critiques informed the 2016 President's Council of Advisors on Science and Technology (PCAST) report Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature-Comparison Methods, which emphasized empirical foundation testing for disciplines like fingerprints and toolmarks, leading the FBI to revise training and testimony guidelines in 2017 to require disclosure of error rates and limitations in court.^[35]^[45] These reforms prompted institutional shifts, including mandatory accreditation for federal labs under ANSI-ASQ standards by 2017 and adoption of proficiency testing in over 80% of state labs by 2020, correlating with documented reductions in contamination incidents per audit data from the American Society of Crime Laboratory Directors.^[55]

Criticisms regarding overreach and unintended consequences

Critics of the Innocence Project, co-founded by Peter Neufeld and Barry Scheck, have argued that its emphasis on DNA exonerations exaggerates the prevalence of wrongful convictions, as these cases represent a narrow subset of total convictions reliant on post-conviction biological evidence unavailable at trial. According to legal scholar Margaret L. Paris, this focus may imply systemic flaws beyond what empirical data supports, potentially eroding public confidence in convictions secured through other means and fostering a perception that the justice system routinely fails without sufficient evidence of broader error rates.^[56] The project's critiques of traditional forensic disciplines, such as hair analysis, bite marks, and toolmark examination—pioneered in part by Neufeld's advocacy—have contributed to stricter admissibility standards, including those recommended in the 2009 National Academy of Sciences report, which highlighted limitations in non-DNA methods. While aimed at preventing miscarriages of justice, these reforms have had unintended consequences, including the exclusion of forensic evidence in ongoing prosecutions, leading prosecutors to drop cases or offer lenient pleas where guilt was probable but proof fell short of elevated scientific validation. For example, the National Association of Criminal Defense Lawyers has questioned whether such exclusions go too far, potentially compromising the ability to convict perpetrators in crimes lacking DNA traces, which constitute the majority of cases.^[57] Additionally, the Innocence Project's prioritization of factual innocence over procedural defenses has drawn criticism for creating a moral hierarchy among clients, where "guilty" defendants receive diminished advocacy, as noted by criminal defense attorney Abbe Smith, who describes an "arrogance" in statements like those from affiliated projects refusing aid to inmates seeking sentence reductions on technicalities. This stance, Smith contends, may train future lawyers to undervalue zealous representation of the factually culpable, inadvertently weakening the broader defense bar's capacity to challenge prosecutorial overreach in non-exoneration contexts.^[58] Reforms spurred by Innocence Project successes, such as enhanced eyewitness protocols and forensic oversight, embody a trade-off: while reducing false positives, they can diminish accurate identifications or evidence reliability, elevating the risk of releasing guilty parties and enabling recidivism at a societal cost disproportionate to wrongful conviction rates, estimated at 0.5-5% for serious crimes. Philosopher Larry Laudan highlights this in analyses of cases like Anthony Porter's, where Innocence Project-affiliated efforts yielded a recanted alibi confession later deemed coerced, illustrating how innocence-focused tactics can introduce new evidentiary flaws without guaranteed net gains in accuracy.^[59]

Publications and writings

Major books and scholarly articles

Neufeld co-authored the book Actual Innocence: Five Days to Execution, and Other Dispatches From the Wrongly Convicted with Barry Scheck and Jim Dwyer, published in 2000 by Doubleday.^[60] The work examines mechanisms of DNA-based exonerations through detailed case studies, highlighting systemic flaws in traditional forensic techniques such as eyewitness misidentification, false confessions, and unreliable serology evidence.^[61] It draws on empirical data from early Innocence Project cases to argue for probabilistic modeling of error rates in criminal investigations, emphasizing causal factors like confirmation bias among examiners.^[62] In scholarly articles, Neufeld addressed forensic DNA litigation challenges in "Have You No Sense of Decency?", published in the Journal of Criminal Law and Criminology in 1993.^[63] The piece critiques the collision of scientific standards and adversarial legal processes, advocating for rigorous validation of probabilistic evidence to prevent miscarriages of justice.^[64] Neufeld co-authored "Invalid Forensic Science Testimony and Wrongful Convictions" with Brandon L. Garrett in the Virginia Law Review in 2009, analyzing trial transcripts from 137 DNA exoneration cases.^[38] The study documents instances of overstated forensic matches in fields like microscopic hair comparison and bite mark analysis, supported by quantitative data showing discrepancies between expert claims and empirical validation rates.^[65] In "The Trajectory of Forensics," published in Duke Law Journal Online in 2019, Neufeld outlined evolving standards for forensic reliability post-National Academy of Sciences reports.^[66] He emphasized first-principles approaches to error quantification, citing datasets from exonerations to underscore persistent issues in subjective pattern-matching disciplines despite policy shifts.^[66]

Reports and policy papers

Neufeld contributed to policy discussions through congressional testimony and organizational briefs emphasizing empirical evidence of forensic science shortcomings. In April 2007, he publicly addressed a city-commissioned report on the New York City Office of Chief Medical Examiner, which documented decades of negligence, including drylabbing, falsified records, and inadequate validation of serological and other analyses, leading to unreliable evidence in hundreds of cases.^[67] In January 2008, Neufeld testified before the U.S. Senate Judiciary Subcommittee on Crime and Drugs, critiquing the Department of Justice's forensic grant programs for failing to enforce rigorous scientific validation and oversight, and advocating for independent accreditation to reduce error rates in fields like serology where pre-DNA false inclusions were prevalent.^[68] As co-director of the Innocence Project, Neufeld supported the organization's amicus curiae brief in Melendez-Diaz v. Massachusetts (2009), which argued that forensic reports—often produced without cross-examination opportunities—violate the Sixth Amendment's Confrontation Clause, drawing on data from DNA exonerations showing forensic analysts' testimony contributed to errors in 60% of reviewed cases involving flawed techniques like microscopic hair comparison and serology.^[69] Neufeld's work informed Innocence Project policy documents quantifying risks in pre-DNA serology, where testimony frequently overstated matching probabilities despite known false positive rates exceeding 1% in controlled studies and contributing to wrongful links in at least 27% of analyzed exonerations, underscoring the need for probabilistic rather than definitive claims in court.^[70]
