content: Look into the Stingray use by domestic cops and you'll find that this is in no way because it hasn't been getting used. The Feds and Marshal Service have both helped local police hide their use of these devices by taking over the records so that they couldn't be grabbed by FOIA requests.  There has been a lot of use of these devices on American soil, and every use siphons up the texts, calls, and location data of tens of thousands of innocent citizens. To use these devices against petty thieves should end up with an officer losing his job, as it's a complete violation of the civil rights of tens of thousands, but we'll never see that happen.
