Canceling a contract with Flock Safety is proving harder than signing one. As more cities move to drop the license-plate-reader company, The Verge reports that just as many are discovering how difficult actually terminating the agreements can be — with Flock reportedly ignoring cancellation requests outright in some cases.

The latest flashpoint is Plymouth, Minnesota, where the city council voted to terminate its Flock contract. Plymouth joins a growing list of municipalities reconsidering their relationships with the surveillance vendor, whose automated license plate reader cameras have drawn mounting scrutiny over privacy, data sharing, and public oversight.

The pattern raises an awkward question for local governments: what recourse does a city have when a vendor simply doesn't process a termination? Contract disputes with surveillance providers typically play out quietly, but a string of cities publicly voting to cancel — and then struggling to make it stick — turns a procurement issue into a political one. For Flock, which built rapid growth on easy municipal adoption, friction on the way out could become as notable as the sales pitch on the way in.
