This documentary provides an excellent analysis of the evidence and raises serious questions about the police and legal procedures in the 1950s. However, it is undermined by numerous film clips, most of a whimsical nature, that are inserted throughout the programmes. Those depicting court scenes could be said to aid a viewer's understanding of how a courtroom would have looked, but the ridiculous clips from US and other movies were out of place and, for me, spoiled the documentary.
