Wrongful convictions are a persistent problem undermining the integrity of the United States criminal justice system. Over 2,700 individuals have been exonerated through DNA testing alone, highlighting the prevalence of this issue (University of Michigan Law School, 2025) []. Often the result of a combination of factors, including mistaken eyewitness testimony, flawed forensic evidence, inadequate legal defense, and prosecutorial misconduct, wrongful convictions have far-reaching consequences (Scheck et al., 2020) []. At the individual level, those who are unjustly imprisoned suffer a variety of setbacks: beyond the physical and mental toll of imprisonment, they face difficulties reacclimating to family life and gaining employment (Offer, 2023). At the societal level, wrongful convictions erode public trust in the justice system and divert resources away from genuine threats to public safety (Jones & Jones, 2022) []. Organizations like the Innocence Project have brought widespread attention to the problem of wrongful convictions, garnering public support and leading successful efforts to reform investigative and forensic evidence collection practices (Cherry, 2020) []. While these reforms have been effective, improving legal defense standards and promoting systemic transparency are also necessary to further reduce the number of wrongful convictions in the United States [].
