Ok I found this: https://www.benthamsgaze.org/2021/07/15/what-went-wrong-with...
Numerous people that rabbithole into this case end up running to a nearby bucket. It is... not pretty.
There are thousands of cases that are hidden in the bowels of the post office court system
Oh and the compensation are uh... let say hard to get the money for.
Every transaction the system touched should be inspected, because I'm sure there were plenty of sub-postmasters who took the "shortfall" at face value and paid up without even thinking about questioning the system.
Having agency in a society ( through democracy, markets, shaping narratives in discussions and many other ways) might just require adults who deal with the horrible aspects society produces in a responsible manner. Which includes not designing solutions for a false peace of mind. After all, you yourself (as in every individual) are the one responsible for the consequences you produce.
Personally i hope this might be a matter of outer alignment, as in a problem of not agreeing on shared goals that you can apply to problem solving in a coordinated manner. Which has to include the ability to verify process and outcome (which unfortunately in itself are highly safety critical) and the unwillingness to accept false but pleasant conclusions with high costs for others.
