Final answer:
The use of sequential lineups is recommended as a modification to improve the reliability of eyewitness testimony during police lineups.
Step-by-step explanation:
The recommended modification to how police lineups are conducted to improve eyewitness testimony reliability is the use of sequential lineups.
To minimize suggestibility and potential bias in eyewitness identification, researchers and legal specialists have suggested several changes. One key modification is conducting police lineups in a sequential manner, where witnesses view each lineup member one at a time, rather than seeing all members simultaneously (traditional simultaneous lineup).
This method reduces the risk of witnesses making relative judgments, which can lead to misidentification. A blind photo lineup is also recommended, ensuring that the person presenting the lineup does not know which photo is the suspect's, thereby decreasing the chance of inadvertently influencing the witness. In addition, some judges inform jurors of the possible flaws in eyewitness identification, or may suppress eyewitness testimony completely if found unreliable.
