The Stingray surveillance technology, also called cell-site simulator technology, can gather a significant amount of personal data from individuals’ cellphones. A recent federal case in New York and a new law in Illinois aim to curtail the warrantless use of Stingrays.
The technology simulates a cellphone tower so that nearby mobile devices will connect to it and reveal sensitive personal data, such as their location, text messages, voice calls, and other information. The Stingray surveillance technology vacuums information from every cellphone within its range, so innocent people’s private data are gathered, as well. It is a dragnet that can capture hundreds of innocent people, rather than just the suspect targeted.
As I have discussed before, law enforcement officials are using this technology in secret. Documents obtained by the ACLU showed that the U.S. Marshals Service directed Florida police to hide the use of Stingray surveillance technology from judges, which meant the police lied in court documents. Sarasota police Sgt. Kenneth Castro sent an e-mail in April 2009 to colleagues at the North Port (Florida) Police Department: “In reports or depositions we simply refer to the assistance as ‘received information from a confidential source regarding the location of the suspect.’” A recent San Diego Union-Tribune investigation showed that local police are using the surveillance technology in routine investigations – not ones involving terrorism or national security.
Now, a federal judge in New York has thrown out Stingray evidence gathered without a warrant. The case is United States v. Lambis (pdf) in the Southern District of New York. Without a warrant, the Drug Enforcement Administration used a powerful cell-site simulator to determine the location of a cellphone was in Raymond Lambis’s home. Agents then searched his home and found drugs and drug paraphernalia. Read more »
