Re: Never trust an AI for things like this
"It goes to show that just because some idiot savant AI decides you have a swimming pool, doesn't mean one exists there."
True, but in the French case, it costs local Government the price of sending a letter to the home owner asking them to confirm if the have an unregistered pool or not. Now the onus is on the home owner to come clean and pay up, deny it and lie to the authorities or point out the authorities error. Either way, it's not costing much more for the local government to ask nicely rather than just send a bill and piss of all the false positive home owners.
The Maryland case you described sounds far worse and clearly DID piss of a lot of people.
