Eyewitness testimony can play a big part in criminal court cases. Whether or not a person is convicted of a crime can come down to the reliability of an eyewitness and how confidently he or she conveys testimony to a jury. The problem is these eyewitness accounts aren't always accurate. The Innocence Project is a nonprofit team of attorneys and law students that re-examines questionable murder convictions with the hope of using DNA evidence to overturn the sentences of defendents who've been wrongfully imprisoned. In the first 130 cases the Innocence Project overturned, eyewitness testimony played a part in 78 percent of those wrongful convictions [source: Stambor].
