Haven't UK learnt anything after unjustly accusing and imprisoning all those people that the Postmaster thoughts had stolen money when it turned out eventually to have been a software bug?
I don't think it was a "bug", but it is probably described as such to minimise what happened. My understanding is that people with admin access were manipulating Postmaster transactions which resulted in creating artificial losses and Post Office was denying it was possible, despite having knowledge it was happening.
