I suggest you keep an eye on what's being published in
Private Eye and
Computer Weekly if you have access to those where you are. They're holding feet to the fire on all these points.
One thing I would say is that if somebody is convicted in the UK, it's acceptable legally and culturally to call them by the crime they committed.
The problem is that in this case the Post Office had unique legal powers, and was being run by people who did not want to "harm the brand" by admitting they had made mistakes, so kept digging.
There is also a fundamental flaw in how the courts - and the Post Office prosecutors - were instructed to think about the evidence in common law.
Bizarrely, it was not (and may still not), be an acceptable defense to say that computer records are wrong. They are assumed correct in UK courts. IT systems were legally considered infallible, and if your evidence contradicts an IT systems evidence, you were considered a liar by the court, and a jury might be instructed accordingly.
Yes, that's awful. Yes, it's ruined lives.
But also, I think all involved have realised pointing fingers at one or two individuals to blame hasn't really helped fix things. Like an air accident, you have to have several things go wrong and compound errors to get into this amount of trouble, normally. There were systemic failing across procurement, implementation, governance, investigations, prosecutions, within the justice system and beyond.
I already know people who have worked for Fujitsu in the UK are not exactly shouting about it. And yet, they're still getting awarded contracts before the compensation has been paid out...
