A grassroots revolt against Flock's license plate cameras is spreading across red and blue towns alike, bad news for the company and the police departments that quietly installed its gear.

• A Sullivan County, Tennessee commissioner told a Flock representative at a public meeting that the company's CEO should be hanged for treason, days before a vote on renewing the contract.
• The anger crosses party lines — rural conservatives, urban progressives and suburbs are all pushing back, mostly because the cameras went up with no public debate.
• Flock is now promising reforms after reports that police used the system to track ex-partners: case numbers required for searches and data deleted after seven days instead of 30.
• Those changes have big holes — emergency searches can skip the case number, and existing contracts keep their old, longer retention rules.
• The deeper complaint is not how long the data is kept but that a private company, not a government anyone can vote out, is running mass surveillance on ordinary drivers.

Outlook: Expect more county votes to cancel or shrink Flock contracts, while the cameras keep spreading faster than towns are pulling them out.
