The four-part mini-series Mr Bates vs The Post Office is worth checking out:
> A faulty IT system called Horizon, developed by Fujitsu, creates apparent cash shortfalls that cause Post Office Limited to pursue prosecutions for fraud, theft and false accounting against a number of subpostmasters across the UK. In 2009, a group of these, led by Alan Bates, forms the Justice for Subpostmasters Alliance. The prosecutions and convictions are later ruled a miscarriage of justice at the conclusion of the Bates & Others v Post Office Ltd judicial case in 2019.[4][5]
