Law Enforcement Using Cell Phone Location Technologyby Doug Mataconis
Yesterday, the Washington Post reported on an alarming increase in the use of cell phone tracking technology by federal law enforcement:
Federal officials are routinely asking courts to order cellphone companies to furnish real-time tracking data so they can pinpoint the whereabouts of drug traffickers, fugitives and other criminal suspects, according to judges and industry lawyers.
In some cases, judges have granted the requests without requiring the government to demonstrate that there is probable cause to believe that a crime is taking place or that the inquiry will yield evidence of a crime. Privacy advocates fear such a practice may expose average Americans to a new level of government scrutiny of their daily lives.
Such requests run counter to the Justice Department’s internal recommendation that federal prosecutors seek warrants based on probable cause to obtain precise location data in private areas. The requests and orders are sealed at the government’s request, so it is difficult to know how often the orders are issued or denied.
But some of those requests have become public, and they show that law enforcement agents are relying on a standard far below probable cause to justify their access to technology that essentially acts as a personal GPS tracking device:
In a stinging opinion this month, a federal judge in Texas denied a request by a Drug Enforcement Administration agent for data that would identify a drug trafficker’s phone location by using the carrier’s E911 tracking capability. E911 tracking systems read signals sent to satellites from a phone’s Global Positioning System (GPS) chip or triangulated radio signals sent from phones to cell towers. Magistrate Judge Brian L. Owsley, of the Corpus Christi division of the Southern District of Texas, said the agent’s affidavit failed to focus on “specifics necessary to establish probable cause, such as relevant dates, names and places.”
Owsley decided to publish his opinion, which explained that the agent failed to provide “sufficient specific information to support the assertion” that the phone was being used in “criminal” activity. Instead, Owsley wrote, the agent simply alleged that the subject trafficked in narcotics and used the phone to do so. The agent stated that the DEA had ” ‘identified’ or ‘determined’ certain matters,” Owsley wrote, but “these identifications, determinations or revelations are not facts, but simply conclusions by the agency.”
Instead of seeking warrants based on probable cause, some federal prosecutors are applying for orders based on a standard lower than probable cause derived from two statutes: the Stored Communications Act and the Pen Register Statute, according to judges and industry lawyers. The orders are typically issued by magistrate judges in U.S. district courts, who often handle applications for search warrants.
In one case last month in a southwestern state, an FBI agent obtained precise location data with a court order based on the lower standard, citing “specific and articulable facts” showing reasonable grounds to believe the data are “relevant to an ongoing criminal investigation,” said Al Gidari, a partner at Perkins Coie in Seattle, who reviews data requests for carriers.
Another magistrate judge, who has denied about a dozen such requests in the past six months, said some agents attach affidavits to their applications that merely assert that the evidence offered is “consistent with the probable cause standard” of Rule 41 of the Federal Rules of Criminal Procedure. The judge spoke on condition of anonymity because of the sensitivity of the issue.
While some judges appear to be holding law enforcement back on this issue, the majority are rubber-stamping the warrant requests, and law enforcement is responding by relying upon the technology in an increasing number of cases.
That cell phone in your pocket may not be watching you, but it can tell Big Brother where you are.
