Gary Dotson became the first American exonerated by DNA after a twenty-five-to-fifty-year sentence.
Eyewitness misidentification contributed to seventy-five percent of the first two hundred thirty DNA exonerations.
Cross-racial identifications are significantly less accurate due to the prevalence of own-race bias.
High stress and weapon focus cause the brain to prioritize threats over specific facial details.
Double-blind lineups prevent police officers from giving unintentional non-verbal cues to witnesses.
Memory functions as a reconstructive storyteller rather than a permanent digital recording of events.
