and mistaken rate increased in a sequential lineup lap when the suspect was present; the error rate increased only when the suspect was absent. US law While many states agree that sequential lineups can reduce wrongful convictions, they also notice that sequential lineups lead to more of a chance that the guilty would be overlooked and not convicted of their crime. Because of this many states do not want to implement a law that mandates sequential lineups. These states accept their benefits but do not want to rule out other types of lineup. There are different feelings about the advantages and disadvantages of sequential lineups. Gronlund, Carlson, Dailey, and Goodsell state one of the disadvantages: "Sequential lineups do not enhance accuracy but rather make eyewitnesses more conservative in their willingness to choose. Although this is desirable when the police have an innocent suspect, it is problematic if the police have a guilty one." But Lindsay, Mansour, Beaudry, Leach, and Bertrand show one of the advantages of sequential lineups estimating that with them between 570 to 1425 innocent people would not be wrongfully convicted that would be with simultaneous lineups. According to the Innocence Project website, many states and law enforcement agencies have started to implement the tools that would be necessary to run double-blind sequential lineups but have yet to fully embrace them. Studies Cutler and Penrod (1988) Brain L. Cutler and Steven D. Penrod conducted this study in 1988 to examine multiple variables' influence on eyewitnesses' accuracy during a lineup. The participants were first given a videotaped store robbery and a questionnaire, then asked to identify the robber in a photo lineup. They were given different videotapes, different lineups, and different instructions. There were 175 participants, all undergraduate college students. The results were: Correct identification rate: 80% for sequential lineups and 76% for simultaneous lineups (total). 78% for sequential lineups and 80% for simultaneous lineups when cues were strong. 84% for sequential lineups and 58% for simultaneous lineups when cues were weak. Mistaken rate in target-absent condition: 19% for sequential lineups and 39% for sequential lineups. In this study, the correct identification rates were very much higher across all situations than normal. They also did not find a significant enough difference in correct identification rate between simultaneous and sequential lineups when the target was present. Most studies found that the correct identification rate is higher for simultaneous lineups. Steblay,
