The Post Office is responsible because they drove the process of: 1) buying broken software and not checking it was fit for purpose 2) Vigorously investigating post masters and not relenting even when many of the people being investigated claimed there must be a problem with the software 3) (and this is the kicker) continuing when they started to realise that maybe the software was the problem Personally I think members of the board at the time need to face some kind of criminal, or at least civil, action here.
