Cops are behind the times with their Stingray. Check it: right here on the Phantom Soapbox, the semi-autonomous flying WiFi and phone sniffer. Geeks built it for a giggle. Its better than FBI kit.
Stingrays are designed to locate a mobile phone even when it's not being used to make a call. The Federal Bureau of Investigation considers the devices to be so critical that it has a policy of deleting the data gathered in their use, mainly to keep suspects in the dark about their capabilities, an FBI official told The Wall Street Journal in response to inquiries.
A stingray's role in nabbing the alleged "Hacker"—Daniel David Rigmaiden—is shaping up as a possible test of the legal standards for using these devices in investigations. The FBI says it obtains appropriate court approval to use the device.
Sometimes it is a burden to be so right, about so many things. ~:D
