Think you’re safe inside your house? Think you’re privacy is protected as long as you’re inside the four walls of your home? Think again. Police agencies all across the country have obtained a piece of equipment called Range-R which can work like finely tuned motion detectors, using radio waves to zero in on movements as slight as human breathing from a distance of more than 50 feet. They can detect whether anyone is inside of a house, where they are and whether they are moving.
At least 50 U.S. law enforcement agencies have secretly equipped their officers with radar devices that allow them to effectively peer through the walls of houses to see whether anyone is inside, a practice raising new concerns about the extent of government surveillance.
Current and former federal officials say the information is critical for keeping officers safe if they need to storm buildings or rescue hostages. But privacy advocates and judges have nonetheless expressed concern about the circumstances in which law enforcement agencies may be using the radars — and the fact that they have so far done so without public scrutiny.
“The idea that the government can send signals through the wall of your house to figure out what’s inside is problematic,” said Christopher Soghoian, the American Civil Liberties Union’s principal technologist. “Technologies that allow the police to look inside of a home are among the intrusive tools that police have.”
Agents’ use of the radars was largely unknown until December, when a federal appeals court in Denver said officers had used one before they entered a house to arrest a man wanted for violating his parole. The judges expressed alarm that agents had used the new technology without a search warrant, warning that “the government’s warrantless use of such a powerful tool to search inside homes poses grave Fourth Amendment questions.”
