House report urges clearer guidance on cellphone technology
WASHINGTON — Clearer guidelines are needed for law enforcement’s use of secretive and intrusive cellphone tracking technology, and police and federal agents should be upfront with a judge about their deployment, a House committee said in a report Monday.
The report from the House Oversight and Government Reform Committee examines the use of cell-site simulators by federal, state and local law enforcement agencies. The technology works by mimicking a cellphone tower, allowing law enforcement to collect basic data — such as a unique subscriber number — from cellphones in a particular area or neighbourhood. The data can help police determine the location of a targeted phone without the user even making a call or sending a text message.
The surveillance devices have been broadly adopted by police departments and federal agencies, which see them as vital in helping track the location of criminal suspects. But the technology has raised Fourth Amendment concerns among privacy advocates for its ability to collect data not only about the targets of an investigation but also innocent bystanders who happen to be within range of the simulator device.
“While law enforcement agencies should be able to utilize technology as a tool to help officers be safe and accomplish their missions, absent proper oversight and safeguards, the domestic use of cell-site simulators may well infringe upon the constitutional rights of citizens to be free from unreasonable searches and seizures, as well as the right to free association,” the report states.
