Over the past two decades, eyewitness researchers have staged crimes to investigate the impact of biased lineup procedures on eyewitness identification accuracy and the results have been remarkably consistent; biased lineups dramatically increase the rate of false identifications of innocent people but have little effect on the rate of correct identifications.
Abstract
The issue naturally arises as to why police use biased lineups, and possible reasons include ignorance, sloppiness, and deliberate intent. Experiments demonstrate that, when asked to construct lineups, people with no special training or knowledge of eyewitness issues select foils similar in appearance to the suspect. Concerns about fairness to the witness and fairness to the accused may not alter the tendency to select foils similar to the suspect. Untrained lineup constructors who know that the suspect is guilty select foils similar to the suspect, while dissimilar foils are selected for lineups only when the lineup constructor is explicitly attempting to create a lineup that will lead witnesses to identify the suspect. These findings indicate that highly biased lineups are the product of intentional police misconduct. It is never appropriate for police officers to decide that no doubt exists in a case, and biased lineups are never acceptable. 17 references
