It's a disgrace that no-one has been prosecuted for this travesty of justice. I don't understand how they were able to rely on falsehoods to get convictions and then not be prosecuted for perjury and conspiracy to pervert the course of justice. There's also the issue of the Post Office "recovering" money from sub post masters that wasn't actually missing - that is surely fraud. There needs to be some lengthy jail terms for the higher-ups responsible for overseeing this.
