Studies indicate that sequential lineups decrease the rate of false alarms at the cost of increasing the rate of lost hits. This paper discusses how policymakers should assess this data, considering measures of probative value and the preference for false acquittals over false convictions. It compares sequential to simultaneous lineups and discusses the compromise position of allowing a second lap to witnesses who do not make an identification after first viewing a sequential lineup.
