The next time you're in California, you might not want to bring your cell phone with you. The California Supreme Court ruled Monday that police can search the cell phone of a person who's been arrested -- including text messages -- without obtaining a warrant, and use that data as evidence.
The ruling opens up disturbing possibilities, such as broad, warrantless searches of e-mails, documents and contacts on smart phones, tablet computers, and perhaps even laptop computers, according to legal expert Mark Rasch.
The ruling handed down by California's top court involves the 2007 arrest of Gregory Diaz, who purchased drugs from a police informant. Investigators later looked through Diaz's phone and found text messages that implicated him in a drug deal. Diaz appealed his conviction, saying the evidence was gathered in violation of the Fourth Amendment, which prohibits unreasonable searches and seizures. The court disagreed, comparing Diaz cell phone to personal effects like clothing, which can be searched by arresting officers.
"The cell phone was an item (of personal property) on (Diaz's) person at the time of his arrest and during the administrative processing at the police station," the justices wrote. "Because the cell phone was immediately associated with defendant’s person, (police were) entitled to inspect its contents without a warrant."
In fact, the ruling goes further, saying essentially that the Diaz case didn't involve an exception -- such as a need to search the phone to stop a "crime in progress." In other words, this case was not an exception, but rather the rule.
Rasch, former head of the Justice Department's computer crime unit, pulled no punches in his reaction to the ruling.
"This ruling isn't just wrong, it's dangerous," said Rasch, now director of cybersecurity and privacy at computer security firm CSC in Virginia. "It's remarkable, because it simply misunderstands the nature of these devices."
The door is open for police to search the entire contents of iPhones or other smart phones that people routinely carry, he said.
"In fact, I would be shocked if police weren't getting instructions right now to do just that," he said.
By applying the "personal property on the defendant's person" standard, Rasch said, the ruling could logically extend to tablets or even laptop computers, he said.
It also flies in the face of established law, which prohibits the warrantless search of briefcases by police, other than a quick search for weapons, Rasch said.
In its ruling, the majority likened cell phone inspection to police inspection of a cigarette pack taken from a suspect, which was ruled a legal search in a prior case. A second ruling was cited involving the search of clothing removed from a suspect.
Rasch said the analogies don't hold, however, as modern phones that can store years' worth of personal information are a far cry from drugs hidden in a cigarette case or clothes pockets.
"There is a process for looking at data inside devices,” he said. “It's called a warrant."
Grants police 'carte blanche'
The California ruling was not unanimous. Dissenting Justice Kathryn Werdegar raised similar concerns in her opinion.
"The majority’s holding ... (grants) police carte blanche, with no showing of exigency, to rummage at leisure through the wealth of personal and business information that can be carried on a mobile phone or handheld computer merely because the device was taken from an arrestee’s person," she wrote. "The majority thus sanctions a highly intrusive and unjustified type of search, one meeting neither the warrant requirement nor the reasonableness requirement of the Fourth Amendment to the United States Constitution."
Jonathan Turley, a Constitutional law expert at George Washington University, took to his blog to raise his concerns about the ruling.
"The Court has left the Fourth Amendment in tatters and this ruling is the natural extension of that trend," he wrote. "While the Framers wanted to require warrants for searches and seizures, the Court now allows the vast majority of searches and seizures to occur without warrants. As a result, the California Supreme Court would allow police to open cell phone files — the modern equivalent of letter and personal messages.”
Diaz’s lawyer, Lyn A. Woodward, has said she plans to appeal the decision to the U.S. Supreme Court. In the meantime, warrantless searches of cell phones are essentially the law of the land in California.
Password-protection of smart phones might be a useful tool to ward off a warrantless search -- it's not clear that an arrested suspect could be compelled to divulge his or her password to police -- but that legal argument has not yet been made.

Feds push for tracking cell phones
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. 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. A jury eventually convicted the duo of multiple bank robbery and weapons charges.
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. 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.
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. U.S. 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.
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. Third Circuit Court of Appeals in Philadelphia that Americans' privacy deserves more protection and judicial oversight than what the administration has proposed.
"This is a critical question for privacy in the 21st century," says Kevin Bankston, an attorney at the Electronic Frontier Foundation who will be arguing on Friday. "If the courts do side with the government, that means that everywhere we go, in the real world and online, will be an open book to the government unprotected by the Fourth Amendment."
Not long ago, the concept of tracking cell phones would have been the stuff of spy movies. 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).
Once a Hollywood plot, now 'commonplace'
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. 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.
Obtaining location details is now "commonplace," says Al Gidari, a partner in the Seattle offices of Perkins Coie who represents wireless carriers. "It's in every pen register order these days."
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. But, he cautions, "if the privacy groups win, the case won't be over. It will certainly be appealed."
CNET was the first to report on prospective tracking in a 2005 news article. 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. 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. Verizon Wireless and T-Mobile logs showing the location of mobile phones at the time calls became evidence in a Los Angeles murder trial.
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. 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. With this method, accuracy depends in part on the density of cell sites.
The Federal Communications Commission's "Enhanced 911" (E911) requirements allowed rough estimates to be transformed into precise coordinates. Wireless carriers using CDMA networks, such as Verizon Wireless and Sprint Nextel, tend to use embedded GPS technology to fulfill E911 requirements. 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.
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. A company called TruePosition, which provides U-TDOA services to T-Mobile, boasts of "accuracy to under 50 meters" that's available "for start-of-call, midcall, or when idle."
A 2008 court order to T-Mobile in a criminal investigation of a marriage fraud scheme, which was originally sealed and later made public, says: "T-Mobile shall disclose at such intervals and times as directed by (the Department of Homeland Security), latitude and longitude data that establishes the approximate positions of the Subject Wireless Telephone, by unobtrusively initiating a signal on its network that will enable it to determine the locations of the Subject Wireless Telephone."
'No reasonable expectation of privacy'
In the case that's before the Third Circuit on Friday, the Bureau of Alcohol, Tobacco, Firearms and Explosives, or ATF, said it needed historical (meaning stored, not future) phone location information because a set of suspects "use their wireless telephones to arrange meetings and transactions in furtherance of their drug trafficking activities."
U.S. 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. Lenihan's ruling, in effect, would require police to obtain a search warrant based on probable cause--a more privacy-protective standard.
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. In addition to a search warrant not being necessary, prosecutors said, because location "records provide only a very general indication of a user's whereabouts at certain times in the past, the requested cell-site records do not implicate a Fourth Amendment privacy interest."
The Obama administration is not alone in making this argument. U.S. 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. That's because Navas only used the cell phone "on public thoroughfares en route from California to New York" and "if Navas intended to keep the cell phone's location private, he simply could have turned it off."
(Most cases have involved the ground rules for tracking cell phone users prospectively, and judges have disagreed over what legal rules apply. Only a minority has sided with the Justice Department, however.)
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. 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.
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. last week. 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.
Gidari, the Seattle attorney, said that wireless carriers have recently extended how long they store this information. "Prior to a year or two ago when location-based services became more common, if it were 30 days it would be surprising," he said.
The ACLU, EFF, the Center for Democracy and Technology, and University of San Francisco law professor Susan Freiwald argue that the wording of the federal privacy law in question allows judges to require the level of proof required for a search warrant "before authorizing the disclosure of particularly novel or invasive types of information." In addition, they say, Americans do not "knowingly expose their location information and thereby surrender Fourth Amendment protection whenever they turn on or use their cell phones."
"The biggest issue at stake is whether or not courts are going to accept the government's minimal view of what is protected by the Fourth Amendment," says EFF's Bankston. "The government is arguing that based on precedents from the 1970s, any record held by a third party about us, no matter how invasively collected, is not protected by the Fourth Amendment."
Update 10:37 a.m. PT: A source inside the U.S. 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. 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. Another member is facing 140 years in prison.

MagicJack's next act: disappearing cell phone fees
The company behind the magicJack, the cheap Internet phone gadget that's been heavily promoted on TV, has made a new version of the device that allows free calls from cell phones in the home, in a fashion that's sure to draw protest from cellular carriers.
The new magicJack uses, without permission, radio frequencies for which cellular carriers have paid billions of dollars for exclusive licenses.
YMax Corp., which is based in Palm Beach, Fla., said this week at the International Consumers Electronics Show that it plans to start selling the device in about four months for $40, the same price as the original magicJack. As before, it will provide free calls to the U.S. and Canada for one year.
The device is, in essence, a very small cellular tower for the home.
The size of a deck of cards, it plugs into a PC, which needs a broadband Internet connection. The device then detects when a compatible cell phone comes within 8 feet, and places a call to it. The user enters a short code on the phone. The phone is then linked to the magicJack, and as long as it's within range (YMax said it will cover a 3,000-square-foot home) magicJack routes the call itself, over the Internet, rather than going through the carrier's cellular tower. No minutes are subtracted from the user's account with the carrier. Any extra fees for international calls are subtracted from the user's account with magicJack, not the carrier.
According to YMax CEO Dan Borislow, the device will connect to any phone that uses the GSM standard, which in the U.S. includes phones from AT&T Inc. and T-Mobile USA. At a demonstration at CES, a visitor's phone with a T-Mobile account successfully placed and received calls through the magicJack. Most phones from Verizon Wireless and Sprint Nextel Corp. won't connect to the device.
Borislow said the device is legal because wireless spectrum licenses don't extend into the home.
AT&T, T-Mobile and the Federal Communications Commission had no immediate comment on whether they believe the device is legal, but said they were looking into the issue. CTIA — The Wireless Association, a trade group, said it was declining comment for now. None of them had heard of YMax's plans.
Borislow said YMax has sold 5 million magicJacks for landline phones in the last two years, and that roughly 3 million are in active use. That would give YMax a bigger customer base than Internet phone pioneer Vonage Holdings Corp., which has been selling service for $25 per month for the better part of a decade. Privately held YMax had revenue of $110 million last year, it says.
U.S. carriers have been selling and experimenting with devices that act similarly to the wireless magicJack. They're called "femtocells." Like the magicJack, they use the carrier's licensed spectrum to connect to a phone, then route the calls over a home broadband connection. They improve coverage inside the home and offload capacity from the carrier's towers.
But femtocells are complex products, because they're designed to mesh with the carrier's external network. They cost the carriers more than $200, though some sell them cheaper, recouping the cost through added service fees. YMax's magicJack is a much smaller, simpler design.
