Stingrays are devices that mimic cell towers, so ANYONE in the area where these devices are operating cellphone calls or text messages go though this device. I repeat its ANYONE, that means you as well as the alleged ‘criminal’ they are attempting to track. They claim it helps solve crimes, however in the process it gathers all your information to. Their argument is totally BOGUS. With today’s technology they could easily create a filter system that would lock out any phone numbers that were not suspect related so they would not be recorded.
