In 1998, Cheshire police arrested Sally Clark and charged her with the murder of her two baby sons. In 1999, she was convicted of their murder and sentenced to life imprisonment. That conviction and sentence was overturned by the Court of Appeal in 2003 and recognised as a gross miscarriage of justice, and Sally Clark was set free, albeit after three years in prison. However, her life had been destroyed, and just four years later she died from alcohol poisoning—the grief had driven her to drink, and it killed her. The destruction of an innocent person’s life was caused by the police, the prosecution and the court swallowing bogus statistical assertions by an alleged expert in her trial. That expert eventually resigned in disgrace, although that did not save Sally Clark. One would think that after that case, Cheshire police and the Crown Prosecution Service would have been very careful to avoid this happening again, and to abide by all the rules and guidelines designed precisely to prevent further terrible miscarriages of justice. Let us test exactly that premise. We are uniquely assisted in the process by the fact that the behaviour of the police and prosecution has been reviewed by two separate police officers, both extremely experienced in precisely this sort of case. The first is Dr Steve Watts, a former assistant chief constable who wrote the national police guidelines on the investigation of deaths in healthcare settings, and the second is former detective superintendent Stuart Clifton—the officer in charge of the investigation that led to the conviction of Beverley Allitt, one of the most prolific child murderers in healthcare history—who was actually commissioned by The Sun newspaper to confirm Letby’s guilt. Indeed, both policemen believed that Letby was guilty—that is, until they examined the hard facts, and both now believe that the Letby case is a serious miscarriage of justice.
