It was very interesting being filmed advising the lawyers on the reliability of the identification evidence in the case of the death of Olive Turner in Birmingham in 1927; and the subsequent hanging of her alleged murderer Joseph Power. There were certainly issues with some of the procedures, which would not be allowed today. Were these procedural problems sufficient to bring his death sentence into question, and this case potentially being a miscarriage of justice?

The only error I need to declare is that I am not officially a forensic psychologist, even though that is how I am described (Reader in Applied Psychology is my correct title).

Note - alluded to in the show was that a street identification of the defendant was first conducted outside a factory prior to the line-up identification. I have also published research on the reliability of a street identification held by the police followed by a line-up here:-
