In 1974, the delving commission was formed in England to examine eye witness procedures after several cases of mistaken identification came to light. Delving (1976) examined all the police line-ups that are commonly referred to as identification parades conducted in England in 1973. In the process, over 2000 parades were analysed and a suspect was identified in 45 per cent of the parades where 82 per cent of those identified were subsequently convicted. The identification comprised the only evidence in over 300 cases and of these 75 per cent of the suspects was found to be guilty showing the compelling real-world evidence that eye witnesses are believed. However, suspects identification in the Devlin report were made in less than half of the cases analysed and it could be argued that the identified suspects were indeed guilty in these cases. The accuracy of the identification was believed to be high and the suspects were guilty thus the eye witnessed should have been believed.
