Interview Dr Karen Renaud & Dr Mike McGuire On Lucy Letby & Post Office Inquiry

Dr Karen Renaud, a computing scientist at the University of Strathclyde, and Dr Mike McGuire, a criminologist at the University of Surrey, join the host to discuss parallels between the Post Office Horizon scandal and the Letby case. The Horizon comparison covers 900 prosecutions between 1999 and 2015 based on flawed software evidence, including ACK failures and undisclosed Fujitsu remote access. Both guests argue that confirmation bias, institutional anchoring, and the silencing of dissent are common features of both cases. Renaud focuses on the way complex technical or scientific evidence can be weaponised against defendants who lack the resources to challenge it, while McGuire situates both cases within a broader pattern of institutional wrongdoing in UK public life. The inadequacy of legal aid funding for expert witnesses is cited as a structural enabler of wrongful conviction.

Dr Karen Renaud

Once an institution decides someone is guilty, every piece of evidence gets interpreted through that lens. That is confirmation bias operating at an institutional level and it is incredibly difficult to reverse.

Dr Mike McGuire

With Horizon, you had 900 prosecutions over sixteen years built on evidence that the Post Office knew was unreliable. The question we should be asking about Lucy Letby is whether the same dynamic was operating.

Dr Karen Renaud

The defendant cannot challenge evidence they cannot see. When the complexity of the evidence — whether it is software logs or medical statistics — exceeds what a lay jury can evaluate, the entire burden falls on cross-examination that never happened.
