That scandal is different in nature but just as egregious. It didn't involve fancy ML or algorithms. The Post Office and Fujitsu knew the system was broken (no correct tracking of transactions) and maliciously prosecuted hundreds of people to cover up their enormous failure. "Expert witnesses" lied on the stand, investigations were obstructed and paperwork burned.
Are there more details on that somewhere? Feels like something that an investigative journalist (or, I guess these days, podcaster) would've dug right into the guts of.
People had been doing that since at least 2011 (there were some rumblings before, but no in-depth reporting by the likes of the BBC AFAIK). Still took close to 10 years to resolve the matter...
