Ruling eases government's efforts for cell phone tracking
A federal court in Massachusetts has ruled that the government doesn't need probable cause to obtain a warrant allowing it to use a person's cell phone to track his past movements...
"This is the first decision that's been about historical tracking," said Jennifer Granick, civil liberties director at the Electronic Frontier Foundation, a privacy advocacy group in Washington.
"The idea is that the government is using this information, that most people don't know their cell phone transmits, in order to track you, and they are arguing for an extremely low standard under this complicated statutory regime," Granick said. "Most people probably consider this information to be very private -- where you travel and where you've been. So the concern is for something so invasive, the government should have to demonstrate that it's information that they really need."
