Vocativ: Police In These 22 States Can Trick Your Cell Phone by Brian Patrick Byrne:
Stingray purchases are so shrouded in secrecy that they’re probably used a lot more than we know
When police turn to technology to catch a criminal, innocent bystanders—and their personal information—get caught in the fray.
At least 55 local and state police departments in 22 states and the District Of Columbia own stingrays, surveillance devices that can dupe your phone into offering up its location and other information, according to the American Civil Liberties Union. At least nine agencies in California own the gadgets. Six local police departments in Maryland and five in North Carolina are also known to have them.
