In the USA and the UK, many thousands of police suspects are identified by
eyewitnesses every year. Unfortunately, many of those suspects are
innocent, which becomes evident when they are exonerated by DNA testing,
often after having been imprisoned for years. It is, therefore, imperative
to use identification procedures that best enable eyewitnesses to
discriminate innocent from guilty suspects. Although police investigators
in both countries often administer line-up procedures, the details of how
line-ups are presented are quite different and an important direct
comparison has yet to be conducted. We investigated whether these two
line-up procedures differ in terms of (i) discriminability (using receiver
operating characteristic analysis) and (ii) reliability (using
confidence–accuracy characteristic analysis). A total of 2249 participants
watched a video of a crime and were later tested using either a six-person
simultaneous photo line-up procedure (USA) or a nine-person sequential
video line-up procedure (UK). US line-up procedure yielded significantly
higher discriminability and significantly higher reliability. The results
do not pinpoint the reason for the observed difference between the two
procedures, but they do suggest that there is much room for improvement
with the UK line-up.
