Marina Hyde is right that there has not been nearly enough outrage about the Post Office/Horizon scandal (Hundreds of lives ruined. Not a single person held to account. And still: silence on the Post Office scandal, 2 May). One of the most disturbing aspects is that Post Office Ltd was allowed to bring private prosecutions, thereby acting as victim, investigator and prosecutor at one and the same time.
Our criminal law system relies on full disclosure of all relevant facts, but Post Office Ltd had already told each defendant that they were the only subpostmasters this had happened to, so they failed that requirement at the first hurdle. They were never going to reveal any failings of the Horizon software to the courts. That the cases were ever allowed to proceed at all on that basis is one of the biggest scandals.
