When they were eventually confronted with the overwhelming evidence of hundreds of false convictions they doubled down because they lack any sense of morality.
So while it is a sad technical tale it is also an indictment of British Board room culture.
The whole sorry affair has been covered by Private Eye magazine for over ten years.
I don't believe you know what their internal mental states are.
If someone knows they are sending innocent people to prison, benefits from doing so, and continues doing so we can reasonably infer they lack morality.
So given a set of actions you can infer a likely set of mental states — this is also done in the court room. Can you always infer with 100% accuracy and with every colorful detail fleshed out? No. Do you typically need to? No.
And we have we gone through that process to look at the issue from all sides and hear arguments from all parties? No.
You don't need to know intent to fire or punish someone anyway. In this case we can dismiss people for improper action, without demeaning them personally.
I agree that one should be cautious with early accusations or hopping on trains just because they are rolling.
Holding executives responsible for their misdeeds is the bare minimum in the meantime.
Having rich people face actual material consequences to their life, rather than "punishments" like losing a job or honor, would hopefully reduce corporate malpractice, yes, as they now know that they are not invincible (obligatory note that I am talking about criminal responsibility, not suggesting we do away with LLCs or something)
I think to achieve that it has to be better in expectancy for someone who knows about the problem (and widely believed by that person too) to act sooner to resolve the problem than to try to cover things up, but I don’t really know what rules would help. For example, maybe an alternative thing that would work would be some kind of whistleblower rules like in finance[1].
In the hypothetical where I am stood with my hand on the lever choosing between stopping the scandal sooner and letting executives off entirely or having more wrongful convictions for longer but later throwing the executives in jail, I will choose the former every time, even though it feels unjust.
[1] In finance the whistleblower rules are designed to incentivise people to not be accomplices to crimes done by their superiors/coworkers. The incentives must be high because, no matter what the rules say about it, whistleblowers will expect to not work in finance again after blowing the whistle. The rules work because those large-scale financial crimes generally are hard to without one’s competent colleagues finding out.
A well designed system, whether a computer or an organization should always have controls that guide things to where they should be. That means carrots and sticks.
In a place like a post office, that means separation of duties, audit, and clear lines of accountability. Things fail when nobody asks awkward questions or looks.
I do think that leadership responsible for a debacle like this must be punished. Their incompetence destroyed lives of innocent people.
The problem here was that as many sub-postmasters were co owned by a husband and wife with children. There was an enormous incentive for one of the sub post masters to plead guilty and say, "my wife had nothing to do with it." Doubly so as the sentences would often be on the cusp of the "suspendible range", a guilty plea combined with contrition is much more likely to get a judge to suspend your sentence if he can.
Of course, this "plea-bargaining" is standard practice in the states but we aren't used to it in the UK.
The issue is that no barrister would allow their client to plead guilty without giving them a little canned speech about not pleading guilty if they didn't do it and having them, "sign their brief".
