Sequential Line Up Experiment in Illinois

Police Departments in Chicago, Evanston and Joliet are experimenting with the sequential line up protocol recommended by some social scientists to improve the accuracy of identification procedures.  Line-ups will be administered by officers who do not know which of the participants is the suspect, and witnesses will not look at the lineup all at once, but will view suspects one at a time, being required to give a yes or no before moving on to the next.  This procedure will be used in half of the lineups.
