The most important part is that the PO used these actions to claw back "stolen" money from its postmasters. This money appears to have ended up in its profit and loss account.

If true this means that instead of the postmasters stealing from the PO, the PO was stealing from its postmasters.

There's been at least one claim - in the Daily Telegraph, so questionably credible, but never mind - that a document exists proving that senior management were aware that the accusations against postmasters were untrue, but carried on regardless.

If that document exists it changes the narrative from accidental tech failure and management incomprehension to something less wholesome.
