In September, Gary Wells, a psychology professor at Iowa State University, released a new report comparing whether the accuracy of lineups improves when the possible suspects are presented to witnesses in sequence, rather than all at once in the traditional lineup.
Our study is thus the first to challenge the critical assumption that memory-related brain activity is automatically elicited when suspects are presented with crime reminders.
The last episode of series three of the complex police corruption drama Line of Duty involved two lengthy interrogations in which suspects were presented – via the interrogators' iPads – with an almost bewildering sequence of evidence samples (pictures of weapons, CCTV images, mobile-phone records) and challenged for explanations.
A study of television news found that black crime suspects were presented in more threatening contexts than whites: black suspects were disproportionately shown in mug shots and in cases where the victim was a stranger".
With the new system, the authorities are using a hand-held scanning device that can check a prisoner's identity in seconds when the suspect is presented in court, said Paul J. Browne, the department's chief spokesman.
To make sure that the police could not unintentionally influence the process, officers who didn't know who the real suspect was presented photos of six people to the eyewitnesses.
In the third section, we evaluate Bayesian measures of eyewitness performance and show that they reflect a complex mixture of true discriminability of guilty from innocent suspects, response bias, and the probability that a guilty suspect is presented to the witness.
Information gain curves and posterior probabilities of guilt reflect a combination of the probability that a guilty suspect is presented to the witness (base rate of TP lineups), the witness's willingness to identify someone (response bias or confidence), and the true discrimination potential provided by the identification procedure.
All the usual sushi suspects are present, from makis bulging with tempura-fried soft shell crab to more austere nigiri.
The usual suspects are present: evil military types, a plucky band of environmentalists and a cast of loveable animals fighting for their survival.
All the usual suspects are present in the gallery of contemporary German art: Richter, Beuys, Baselitz, Polke, each grappling in his own way with national trauma and repression (as signified by Richter's blurry photo-painting of Freud).
