Eyewitness ID
According to the Innocence Project, approximately 69% of the more than 375 DNA-based exonerations nationwide involved mistaken eyewitness identifications. However, there are ways to prevent this, including reforms to police department procedures.

NACDL supports changes in eyewitness procedures that are proven to increase the reliability of eyewitness testimony without impeding police investigations. Among the most important reforms is the adoption “double blind” sequential lineup procedures, in which suspects are shown one by one to the witness. This reduces the possibility of the witness picking the person who looks most like the culprit. This also means that the procedure is conducted by a police officer who does not know the identity of the suspect, which thus prevents the officer from unconsciously or consciously providing cues to the witness.

Eyewitness ID State Reform
In 2021, the Colorado legislature passed HB21-1142, which limits the use of showups by law enforcement and requires law enforcement agencies to collect certain data each time the technique is used.
