You mean like expert witness polygraphers that were treated as fact by the courts for years and still used to re-incarcerate people on parole/probation? Or gun matching (ballistics) that are no longer considered conclusive but subjective? https://www.mdcourts.gov/data/opinions/coa/2023/10a22.pdf https://www.mdcourts.gov/data/opinions/coa/2023/10a22.pdf Hair and Fiber expert analysis that was wrong? https://innocenceproject.org/fbi-agents-gave-erroneous-testimony-in-at-least-90-of-microscopic-hair-analysis-cases/ https://innocenceproject.org/fbi-agents-gave-erroneous-testi... Or do you mean bite mark analysis that was again wrong?
