Americans’ Cellphones Targeted in Secret U.S. Spy Program - WSJ - WSJ

The latest in domestic surveillance innovation...

"By taking the program airborne, the government can sift through a greater volume of information and with greater precision, these people said. If a suspect’s cellphone is identified, the technology can pinpoint its location within about 10 feet, down to a specific room in a building. Newer versions of the technology can be programmed to do more than suck in data: They can also jam signals and retrieve data from a target phone such as texts or photos. It isn’t clear if this domestic program has ever used those features.

Similar devices are used by U.S. military and intelligence officials operating in other countries, including in war zones, where they are sometimes used to locate terrorist suspects, according to people familiar with the work. In the U.S., these people said, the technology has been effective in catching suspected drug dealers and killers. They wouldn’t say which suspects were caught through this method."
