Over the past several years, there has been a transformation in the ways we think about wrongful convictions. We've come to understand the dangers and prevalence of faulty forensic or "junk" science (e.g., bite mark evidence, firearm tool mark analysis, once-foundational tenets of arson investigations), jailhouse informants, cross-racial eyewitness identifications, and police and prosecutorial misconduct. This knowledge has had a tangible impact on our clients at the Pennsylvania Innocence Project. Though the barriers to overturning a wrongful conviction remain staggering—particularly here in Pennsylvania, where jurisdictional bars to reviewing a conviction hold firm even in the face of compelling evidence of actual innocence—this awareness has led directly to innocent Pennsylvanians coming home.
