(This book) contains all the material for a devastating indictment of the adversarial system of justice as now practised. The facts speak for themselves. The police did behave badly; but … the human capacity for self deception is so strong that the police can, and do, convince themselves of the truth of what they would like to believe. I am also of the opinion that a judicial element should be introduced into police investigations at an early stage, as in France and to a limited extent in Scotland.
The English legal system is not concerned with the proof of innocence but with proof of guilt. This is why the Court of Appeal did not make any findings as to the innocence of the three appellants.
