The Postal Service has started putting cameras on its vehicles that continuously scan roads, map sidewalks, and capture license plates. The pilot began in Washington, DC, and the agency's own words point toward scaling the idea to communities across the country. Mail carriers drive past your home every day. A public institution Americans trust is being turned into a rolling data collector, and petitioners say no law authorized it and the public was never asked. Nobody has explained what is being recorded, who can see it, or how long it is kept. Surveillance that grows quietly, one pilot at a time, becomes permanent before anyone votes on it. Congress writes the rules for the Postal Service and can set hard limits. Halt the Postal Service's camera surveillance program, require public hearings on the data it collects, and write strict limits on postal vehicle surveillance into law.
