Surveillance aimed at one person is rarely confined to one person, and in at least one widely deployed technology the indiscriminacy is the design. A cell-site simulator, commonly called a Stingray, works by impersonating a mobile network tower. Phones in range cannot tell the difference, so they connect and identify themselves. That includes the phone the operator is looking for and every other phone nearby — neighbours, passers-by, people in adjacent flats, anyone in a hospital or a place of worship within the radius. The bystander collection is not an error; it is how the device locates the target at all. What surrounded that capability is documented too. The FBI required local police departments to sign non-disclosure agreements as a condition of acquiring the equipment, and the American Civil Liberties Union obtained and published them. Departments concealed the technology's use from defence lawyers and from judges, and in some cases prosecutors dropped charges rather than disclose in open court how a defendant had been found. The Pasco County programme shows the same shape without any exotic equipment: the people repeatedly visited were not only those on the list but the households around them — parents, siblings, grandparents cited for uncut grass and missing house numbers because someone under that roof had been designated. Whether or not a given system is aimed at one person, the record shows the burden of it lands on everyone within reach.
- A cell-site simulator impersonates a network tower; every phone in range connects and identifies itself, not only the target's
- Bystander collection is intrinsic to how the device locates a target, not an incidental fault
- The FBI required non-disclosure agreements from local departments acquiring the equipment; the ACLU obtained and published them
- Use was concealed from defence counsel and courts, and charges were dropped in some cases rather than disclose the method
- Pasco County: households around a listed person — parents, siblings, grandparents — were repeatedly visited and cited
Open questions
- This describes capability and documented practice. It does not establish that any particular person was ever incidentally collected.
- Policy has changed in places since the non-disclosure agreements were published, and this concept does not track current practice in any given jurisdiction.
- Nothing here establishes coordination between the technologies described, or that any of them was directed at any individual.

This concept reports documented capability and published practice. It establishes no surveillance of any individual, and no current practice by any named agency.
