just to be clear, close enough but they wont pinpoint it within a few feet or anything. So usually wont be used as evidence on its own.
Still not bad idea.
Stingray devices are more about intercepting messages than radio location.
But any only who has direct control of information from a receiver (such as a stingray device) can radio locate.
Thing is the accuracy is going to be pretty low unless you have multiple receivers.
To give you an idea a single receiver if you know the exact power output of the transmitter will only roughly tell you the distance the transmitter is from the antenna, it wont tell you what direction. With multiple antennas spaces a distance apart from each other (cant all be in one small location) you can start to narrow that down.
So generally they will have a hard time, especially in an urban setting where signal reflections are high, to pinpoint an exact location. But if they just want to know "were you on this particular block at this particular time" they can probably figure that much out.
