New documents obtained by Motherboard using a Freedom of Information request show how Amazon, Ring, a GPS tracking company, and the U.S. Postal Inspection Service collaborated on a package sting operation with the Aurora, Colorado Police Department in December. From the report: The operation involved equipping fake Amazon packages with GPS trackers, and surveilling doorsteps with Ring doorbell cameras in an effort to catch someone stealing a package on tape. The documents show the design and implementation of a highly elaborate public relations stunt, which was designed both to endear Amazon and Ring with local law enforcement, and to make local residents fear the place they live. The parties were disappointed when the operation didn’t result in any arrests. The Aurora Police Department received 25 Amazon boxes, Amazon-branded tape, and Amazon lithium ion stickers as a part of the operation. It also received 15 Ring doorbell cameras and 15 GL300W GPS trackers from 7P Solutions. “Operation Grinch Grab,” as it was called internally, involved seven Aurora zip codes. These companies spent days with the Aurora Police Department preparing them for the operation, and discussing local news coverage and rewriting press releases.
