Following a crime report, the police in England and Wales may use a street identification (showup) to obtain evidence when there is insufficient evidence to arrest. This may involve encouraging a witness to view an individual, or to conduct an area search of the vicinity. The aim of this research was to survey police use of street identifications, comparing outcomes with alternative visual procedures and to extrapolate national estimates of use.
Case data involving identification procedures were obtained from four police forces. These included street identifications, familiar suspect identifications, CCTV evidence, ‘mug shot’ images, facial composites and video lineups.
Three types of data were collected. Firstly, diary studies of robbery squad officers provided details of 701 cases involving an identification procedure and their outcomes. Secondly, data of 37 cases in which positive street identifications were followed by a video lineup of the same suspect. Finally, data of 80 cases in which an area search was conducted with or without a witness present in a police vehicle.
A street identification was attempted in approximately 25% of robberies and was the most frequently used identification procedure. Approximately, 12% resulted in a suspect identification. The majority (66%) were later charged or cautioned, particularly if a witness identified the same suspect in a subsequent video lineup.
The police rely on street identification in the investigation of street robbery. Despite a modest success rate, it is more likely than any alternative procedure to result in a suspect being charged.
