O risco testemunhal

"Nearly 300 American men and women wrongly convicted of crimes have been exonerated by DNA testing. And in the bulk of those cases — almost 75% — the convictions were based in part on faulty eyewitness identifications.
Witnesses are often asked to identify suspects from photo lineups, which are typically conducted by the officers investigating a crime. But numerous scientific studies on memory and identification have demonstrated that witnesses can be influenced, intentionally or not, by the person conducting a lineup. An officer who believes one of the people in a photo lineup is the likely perpetrator can influence — sometimes without even meaning to — the proceeding."
