They indicate that unless the root causes of conviction error are identified, the routine explanations of error (e.g., eyewitness identifications; false confessions) will continue to re-occur. Identifying structural problems may help to prevent future wrongful convictions. The research involves the coding of archival data from the Innocence Project for seventeen cases, including the one for the Central Park Five exonerees. The data were coded by Hartwick College and Northern Vermont University students …
