Which of the following is one way to reduce the likelihood a witness to a crime will pick an innocent person from a police photo lineup?
A) Make sure the investigator asking the witness questions knows which photo is of the suspect.
B) Tell the witness that the person who committed the crime is definitely one of the people in the photos.
C) Show the photos one at a time, not all at once.
D) Tell the witness that they have to pick someone, even if they are unsure.
Answer: C
Rationale: When an entire lineup is shown simultaneously, the witness may assume one of the people is guilty and settle on the best candidate. If the persons in the lineup are presented one at a time, witnesses are less likely to pick out an incorrect suspect because they are willing to consider the next person in the sequence. The other options would actually increase the rate of false identifications.
