The government has their own cell phone tracker called The Stingray which was brought up in a court case. Once brought up in the court case to the judge the government was unwilling to reveal the full details. It was recently revealed in a criminal case in Arizona. Asked if it requires a search warrant, the government filed a memo basically arguing both ways: it said Stingray use generally doesn’t require a warrant, but concedes that one was required in this specific instance — a huge concession that could cost them the case, just so the Stingray’s design and functionality remain a secret.
Although the government’s lawyers are willing to tie themselves in knots trying to conceal the Stingray, we do have some information on how it works: experts told the WSJ that it mimics an actual cell tower pinging for a specific device, and the data can be used to triangulate a phone’s location. It can be concealed in the back of a van and measure the distance to any type of cell phone from multiple locations — circles drawn from each point will intersect within 100 meters of the phone’s location. Our FBI contact told us that tracking a cellphone normally requires a wireless provider’s cooperation, which could take weeks to obtain — the Stingray simplifies investigations because cell towers aren’t needed. We’ll see what happens — if it comes down to keeping the Stingray a secret or allowing law enforcement to track anyone they want without a warrant, we suppose we prefer the first.
I bet its on the black market now….
