Warrantless cell phone tracking has become a powerful and widely used surveillance tool for police officials who use it aggressively with little or no court oversight.
Police in many states have switched tactics by obtaining mobile data to zero in on someone's prior movement and by tracking them through their cell phones, usually without a warrant. In April, the  American Civil Liberties Union (ACLU) released an extensive study of state, federal, and local law enforcement's surveillance practices that illustrate how police track citizens through their cell phones. After poring over 5,500 pages of records in responses from over 200 local law enforcement agencies, the ACLU researchers reported that "only a tiny minority" -- 10 agencies total -- had obtained a warrant before tracking someone through his or her cell phone.
The ACLU is calling for law enforcement agencies to desist from using cell phone tracking without a warrant, and is calling on state and federal lawmakers to pass legislation requiring a warrant before police use location tracking in non-emergency situations. Another Senate effort, Judiciary Committee chair Senator Patrick Leahy's (D-VT) Electronic Communications Privacy Act Amendments Act, Senate Bill 2011, offers a partial repair of the problem. Warrantless cell phone tracking "should be illegal," said Washington, DC, appellate attorney Stephan Leckar, who successfully represented DC nightclub owner Antoine Jones in the case cited above.
In that case, the Supreme Court reversed Jones' conviction and sentence of life without parole in a cocaine trafficking case after they found substantial evidence that the FBI placed a GPS device on Jones vehicle for 28 days without a search warrant. According to Leckar, the "third-party" doctrine is a means for law enforcement to get around the Fourth Amendment. While privacy advocates like the ACLU's Crump argue that cell phone users should get the same protections against warrantless tracking as people subjected to GPS devices being surreptitiously placed on their vehicles, the Justice Department disagrees. Most, but not all, recent state and federal court decisions in major drug cases have upheld the right of police to either track cell phones or search them for evidence in an investigation. In that case, federal prosecutors had subpoenaed MetroPCS and T-Mobile to hand over sixty days of cell phone location data belonging to drug suspects.
As the law now stands, cell phone customers who value their privacy are at the mercy of law enforcement and their wireless service providers. Our favorite carriers, including AT&T, Verizon, T-Mobile and Sprint, are in on the action by selling information to police of a person's whereabouts, including the sale of private text messages and cell tower data, which pinpoint the location where someone is using a cell, the New York Times reported in March. The Times found that T-Mobile charges law enforcement $150 per-hour for cell phone data that shows the approximate location of the tower that a cell phone "pings" off of when the user makes a call. Verizon Wireless, on the other hand, charges  $30-$60 for 15 minutes' worth of tower data, while AT&T charges $75 hourly (a minimum of two to four hours per tower) for a Cell Tower Dump or Cell Site Usage Report. The Times also found that Sprint once billed the Raleigh, North Carolina, Police Department at a "reduced rate" of $50 for an historic tower search and added $30 more for a search of "L-Site GPS pings," while the ACLU reported that Sprint had billed the Phoenix Police Department $460 for the GPS "pings" over a two-day period in 2009. Not only are the wireless providers profiting from your privacy by working with the police, they are lobbying to be able to continue to do so. On the legal front, with state and federal courts split in their decisions on whether warrantless phone tracking violates the Fourth Amendment, the tens of millions of Americans who use cell phones and smart phones will have to wait for the Supreme Court to be the final arbiter.
Clarence Walker is a veteran Houston-based journalist who writes on criminal justice issues. The Obama administration will tell federal judges in New Orleans today that warrantless tracking of the location of Americans' mobile devices is perfectly legal. Federal prosecutors are planning to argue that they should be able to obtain stored records revealing the minute-by-minute movements of mobile users over a 60-day period -- in this case, T-Mobile and MetroPCS customers -- without having to ask a judge to approve a warrant first.
The case highlights how valuable location data is for police, especially when it's tied to devices that millions of people carry with them almost all the time.
In a legal brief (PDF) filed before the Fifth Circuit in February, the Justice Department says its position "is consistent with the Fourth Amendment because a customer has no privacy interest in cell-site records, which are business records created and stored by a cell phone provider in its ordinary course of business." It wants location data collected even if the mobile device isn't being used. Lending a boost to arguments made by the EFF and the ACLU -- and, in separate briefs, the Electronic Privacy Information Center and law professor Susan Freiwald -- is a recent ruling by the U.S. The Justice Department's position is straightforward: a wireless customer "has no reasonable expectation of privacy" in location data, in part because he or she has "voluntarily conveyed" that information to a wireless provider. Prosecutors say all that's necessary is what's known as a 2703(d) order, which requires law enforcement to demonstrate that the records are "relevant and material to an ongoing criminal investigation." Because that standard is easier to meet than that of a search warrant based on probable cause, it's less privacy-protective. Prosecutors had requested any information regarding "the antenna tower and sector to which the cell phone sends its signal," which can yield a location fix down to as a little as a few hundred feet, depending on the tower placement and the technology used. No matter what the outcome of today's arguments before the Fifth Circuit, the losing side is nearly certain to appeal. Two years ago, when the FBI was stymied by a band of armed robbers known as the "Scarecrow Bandits" that had robbed more than 20 Texas banks, it came up with a novel method of locating the thieves. FBI agents obtained logs from mobile phone companies corresponding to what their cellular towers had recorded at the time of a dozen different bank robberies in the Dallas area.
Even though police are tapping into the locations of mobile phones thousands of times a year, the legal ground rules remain unclear, and federal privacy laws written a generation ago are ambiguous at best.


In that case, the Obama administration has argued that warrantless tracking is permitted because Americans enjoy no "reasonable expectation of privacy" in their--or at least their cell phones'--whereabouts.
Those claims have alarmed the ACLU and other civil liberties groups, which have opposed the Justice Department's request and plan to tell the U.S.
Whether state and federal police have been paying attention to Hollywood, or whether it was the other way around, cell phone tracking has become a regular feature in criminal investigations. Obtaining location details is now "commonplace," says Al Gidari, a partner in the Seattle offices of Perkins Coie who represents wireless carriers. Gidari says that the Third Circuit case could have a significant impact on police investigations within the court's jurisdiction, namely Delaware, New Jersey, and Pennsylvania; it could be persuasive beyond those states. And a mobile phone's fleeting connection with a remote cell tower operated by Edge Wireless is what led searchers to the family of the late James Kim, a CNET employee who died in the Oregon wilderness in 2006 after leaving a snowbound car to seek help. The way tracking works is simple: mobile phones are miniature radio transmitters and receivers. The Federal Communications Commission's "Enhanced 911" (E911) requirements allowed rough estimates to be transformed into precise coordinates. T-Mobile, for instance, uses a GSM technology called Uplink Time Difference of Arrival, or U-TDOA, which calculates a position based on precisely how long it takes signals to reach towers. Lenihan's opinion (PDF)--which, in an unusual show of solidarity, was signed by four other magistrate judges--noted that location information can reveal sensitive information such as health treatments, financial difficulties, marital counseling, and extra-marital affairs.
In its appeal to the Third Circuit, the Justice Department claims that Lenihan's opinion "contains, and relies upon, numerous errors" and should be overruled.
Cellular providers tend not to retain moment-by-moment logs of when each mobile device contacts the tower, in part because there's no business reason to store the data, and in part because the storage costs would be prohibitive. Verizon Wireless keeps "phone records including cell site location for 12 months," Drew Arena, Verizon's vice president and associate general counsel for law enforcement compliance, said at a federal task force meeting in Washington, D.C. Gidari, the Seattle attorney, said that wireless carriers have recently extended how long they store this information. Jones, in which the high court forbade the warrantless use of GPS tracking devices to surveil people's movements, law enforcement and the Obama administration are scrambling -- not to find ways to comply with the spirit of the ruling, but to find ways around it.
Whenever a cell phone is used, it "pings" an electronic signal to the nearest cell phone tower, allowing law enforcement to use the cell phone to find or track people. Senate Bill 1212, the Geolocation Privacy and Surveillance (GPS) Act, is sponsored in the Senate by Senators Ron Wyden (D-OR) and Mark Kirk (R-IL). It includes a warrant requirement for real-time tracking, but not for historical location information.
In March, the US 7th Circuit Court of Appeals upheld a warrantless search of a cell phone by Indiana police, a phone belonging to a  meth dealer identified as Abel Flores Lopez. And the wireless service providers are all too happy to work with law enforcement voluntarily, and turn a tidy profit doing it.
Some companies are marketing surveillance fees to law enforcement to spy on targets even though wireless carriers declare that they don't sell their customers' information to police. It found that Alltel provides a faxed listing of an electronic "Tower Dump" for specific times and dates. Cell Site Usage also includes subscriber information for the location, date and time when a phone was used. Even as the debate rages over warrantless cell phone tracking, cell carriers are geared up to oppose legislation that would force the companies to publicly report the number of times their employees provide cell phone location information to police and federal agents. Mark Leno (D-San Francisco), which would prohibit carriers from revealing data to police without a warrant. Motivated by the ACLU research and news reports on the controversy surrounding  warrantless cell phone tracking, US Senator Al Franken (D-Minnesota) recently convened a Senate Judiciary Committee hearing to gather support for the GPS Act. Records kept by wireless carriers can hint at or reveal medical treatments, political associations, religious convictions, and even whether someone is cheating on his or her spouse. Jerry Brown, a Democrat, vetoed (PDF) a bill that would have required law enforcement to obtain location warrants. More than seven years later, the legal landscape remains unsettled, with two other appeals courts taking differentapproaches, and plenty of lower courts disagreeing.
Attorney Kenneth Magidson, one of the Justice Department prosecutors who told an appeals court that Americans enjoy "no reasonable expectation of privacy" in their minute-by-minute movements. The voluminous records showed that two phones had made calls around the time of all 12 heists, and that those phones belonged to men named Tony Hewitt and Corey Duffey. On Friday, the first federal appeals court to consider the topic will hear oral arguments (PDF) in a case that could establish new standards for locating wireless devices.


Third Circuit Court of Appeals in Philadelphia that Americans' privacy deserves more protection and judicial oversight than what the administration has proposed. In 1998's "Enemy of the State," Gene Hackman warned that the National Security Agency has "been in bed with the entire telecommunications industry since the '40s--they've infected everything." After a decade of appearances in "24" and "Live Free or Die Hard," location-tracking has become such a trope that it was satirized in a scene with Seth Rogen from "Pineapple Express" (2008). It comes in two forms: police obtaining retrospective data kept by mobile providers for their own billing purposes that may not be very detailed, or prospective data that reveals the minute-by-minute location of a handset or mobile device.
In a subsequent Arizona case, agents from the Drug Enforcement Administration tracked a tractor trailer with a drug shipment through a GPS-equipped Nextel phone owned by the suspect.
A cellular tower knows the general direction of a mobile phone (many cell sites have three antennas pointing in different directions), and if the phone is talking to multiple towers, triangulation yields a rough location fix.
Wireless carriers using CDMA networks, such as Verizon Wireless and Sprint Nextel, tend to use embedded GPS technology to fulfill E911 requirements.
Magistrate Judge Lisa Lenihan in Pennsylvania denied the Justice Department's attempt to obtain stored location data without a search warrant; prosecutors had invoked a different legal procedure.
They do, however, keep records of what tower is in use when a call is initiated or answered--and those records are generally stored for six months to a year, depending on the company. Warrantless cell phone tracking "has become a powerful and widely used surveillance tool for police officials, with hundreds of departments, large and small, often using it aggressively with little or no court oversight," the report found.
The listing is "no charge," but the company charges a flat rate of $500 for those searches. At the hearing, Franken unveiled a letter he had written to Attorney General Holder seeking information on Justice Department cell phone tracking activity, what the department's stance on the standard for requests for historical location data (cell sites, GPS data), and whether the department had changed its practices in the light of the Jones decision.
Meanwhile, a coalition of tech companies and advocacy groups including AT&T, Facebook, and Google has been all but begging Congress to update the law to require warrants. The January opinion, written by Justice Antonin Scalia, said that the customary law enforcement practice of installing physical GPS bugs on a car for 28 days was a "physical intrusion" and trespass that triggered the Fourth Amendment. Department of Justice lawyers say that "a customer's Fourth Amendment rights are not violated when the phone company reveals to the government its own records" that show where a mobile device placed and received calls. Texas DEA agents have used cell site information in real time to locate a Chrysler 300M driving from Rio Grande City to a ranch about 50 miles away.
AT&T and T-Mobile comply with E911 regulations using network-based technology that computes a phone's location using signal analysis and triangulation between towers. Lenihan's ruling, in effect, would require police to obtain a search warrant based on probable cause--a more privacy-protective standard. District Judge William Pauley, a Clinton appointee in New York, wrote in a 2009 opinion that a defendant in a drug trafficking case, Jose Navas, "did not have a legitimate expectation of privacy in the cell phone" location.
Arena said the company keeps "phone bills without cell site location for seven years," and stores SMS text messages for only a very brief time.
Attorney's Office for the northern district of Texas, which prosecuted the Scarecrow Bandits mentioned in the above article, tells me that this was the first and the only time that the FBI has used the location-data-mining technique to nab bank robbers. Zoe Lofgren, a Democrat representing Silicon Valley, introduced pro-warrant federal legislation. Verizon Wireless and T-Mobile logs showing the location of mobile phones at the time calls became evidence in a Los Angeles murder trial. It's also worth noting that the leader of this gang, Corey Duffey, was sentenced last month to 354 years (not months, but years) in prison.
The bills would require law enforcement agents to obtain a warrant in order to access location information. Santana got 75 years after failing to assist the government with valuable information on other drug dealers.
