How accurate are eyewitnesses to a crime?

Eyewitness testimony — it’s often thought of as solid evidence in criminal cases, but researchers including Iowa State University’s Gary Wells have found that our memories aren’t as reliable as we think. Sometimes, we can even build false recollections about people we only think we saw.

Why are police lineups never perfect?

After each photograph or person, the witness says yes or no. Some research suggests that sequential lineups make it less likely that a witness will finger the wrong person. This is because, in a simultaneous lineup, the witness may feel like they have to pick someone—even if the real culprit is not in the lineup.

Do eyewitnesses provide accurate testimony?

Eyewitness testimony is a potent form of evidence for convicting the accused, but it is subject to unconscious memory distortions and biases even among the most confident of witnesses. So memory can be remarkably accurate or remarkably inaccurate. Without objective evidence, the two are indistinguishable.

How many people are there in a police lineup?

This can be done using a live lineup of people or, as more commonly done in U.S. police departments, a lineup of photographs. Live lineups typically use five or six people (a suspect plus four or five fillers) and photo lineups six or more photographs. [4]

What do police lineup administrators say to witnesses during a lineup?

Experts suggest that lineup administrators might—whether purposefully or inadvertently—give the witness verbal or nonverbal cues as to the identity of the suspect. For instance, if an eyewitness utters the number of a filler, the lineup administrator may say to the witness, “Take your time . . . . Make sure you look at all the photos.”

What is a double-blind lineup in law enforcement?

In a “double-blind” lineup, however, neither the administrator nor the witness knows the identity of the suspect, and so the administrator cannot influence the witness in any way. [8] ( See graphic, “Live Police Lineups: How Do They Work?”)

How effective are double blind sequential photo lineups?

Data collected from approximately 700 photo arrays and live lineups from urban, suburban, and semi-rural Illinois police departments revealed that the double-blind sequential procedure resulted in an overall higher rate of false identifications and a lower rate of “suspect picks” than the simultaneous lineup.
