Most Americans carry cellphones, but many may not know that government agencies can track their movements through the signals emanating from the handset.

In recent years, law enforcement officials have turned to cellular technology as a tool for easily and secretly monitoring the movements of suspects as they occur. But this kind of surveillance - which investigators have been able to conduct with easily obtained court orders - has now come under tougher legal scrutiny.

In the last four months, three federal judges have denied prosecutors the right to get cellphone tracking information from wireless companies without first showing "probable cause" to believe that a crime has been or is being committed. That is the same standard applied to requests for search warrants.

The rulings, issued by magistrate judges in New York, Texas and Maryland, underscore the growing debate over privacy rights and government surveillance in the digital age.

With mobile phones becoming as prevalent as conventional phones (there are 195 million cellular subscribers in this country), wireless companies are starting to exploit the phones' tracking abilities. For example, companies are marketing services that turn phones into even more precise global positioning devices for driving or allowing parents to track the whereabouts of their children through the handsets.

Not surprisingly, law enforcement agencies want to exploit this technology, too - which means more courts are bound to wrestle with what legal standard applies when government agents ask to conduct such surveillance.

Cellular operators like Verizon Wireless and Cingular Wireless know, within about 300 yards, the location of their subscribers whenever a phone is turned on. Even if the phone is not in use it is communicating with cellphone tower sites, and the wireless provider keeps track of the phone's position as it travels. The operators have said that they turn over location information when presented with a court order to do so.

The recent rulings by the magistrates, who are appointed by a majority of the federal district judges in a given court, do not bind other courts. But they could significantly curtail access to cell location data if other jurisdictions adopt the same reasoning. (The government's requests in the three cases, with their details, were sealed because they involve investigations still under way.)

"It can have a major negative impact," said Clifford S. Fishman, a former prosecutor in the Manhattan district attorney's office and a professor at the Catholic University of America's law school in Washington. "If I'm on an investigation and I need to know where somebody is located who might be committing a crime, or, worse, might have a hostage, real-time knowledge of where this person is could be a matter of life or death."

Prosecutors argue that having such information is crucial to finding suspects, corroborating their whereabouts with witness accounts, or helping build a case for a wiretap on the phone - especially now that technology gives criminals greater tools for evading law enforcement.

The government has routinely used records of cellphone calls and caller locations to show where a suspect was at a particular time, with access to those records obtainable under a lower legal standard. (Wireless operators keep cellphone location records for varying lengths of time, from several months to years.)

But it is unclear how often prosecutors have asked courts for the right to obtain cell-tracking data as a suspect is moving. And the government is not required to report publicly when it makes such requests.

Legal experts say that such live tracking has tended to happen in drug-trafficking cases. In a 2003 Ohio case, for example, federal drug agents used cell tracking data to arrest and convict two men on drug charges.

Mr. Fishman said he believed that the number of requests had become more prevalent in the last two years - and the requests have often been granted with a stroke of a magistrate's pen.

Prosecutors, while acknowledging that they have to get a court order before obtaining real-time cell-site data, argue that the relevant standard is found in a 1994 amendment to the 1986 Stored Communications Act, a law that governs some aspects of cellphone surveillance.

The standard calls for the government to show "specific and articulable facts" that demonstrate that the records sought are "relevant and material to an ongoing investigation" - a standard lower than the probable-cause hurdle.

The magistrate judges, however, ruled that surveillance by cellphone - because it acts like an electronic tracking device that can follow people into homes and other personal spaces - must meet the same high legal standard required to obtain a search warrant to enter private places.

"Permitting surreptitious conversion of a cellphone into a tracking device without probable cause raises serious Fourth Amendment concerns, especially when the phone is monitored in the home or other places where privacy is reasonably expected," wrote Stephen W. Smith, a magistrate in Federal District Court in the Southern District of Texas, in his ruling.

"The distinction between cell site data and information gathered by a tracking device has practically vanished," wrote Judge Smith. He added that when a phone is monitored, the process is usually "unknown to the phone users, who may not even be on the phone."

Prosecutors in the recent cases also unsuccessfully argued that the expanded police powers under the USA Patriot Act could be read as allowing cellphone tracking under a standard lower than probable cause.

As Judge Smith noted in his 31-page opinion, the debate goes beyond a question of legal standard. In fact, the nature of digital communications makes it difficult to distinguish between content that is clearly private and information that is public. When information is communicated on paper, for instance, it is relatively clear that information written on an envelope deserves a different kind of protection than the contents of the letter inside.

But in a digital era, the stream of data that carries a telephone conversation or an e-mail message contains a great deal of information - like when and where the communications originated.

In the digital era, what's on the envelope and what's inside of it, "have absolutely blurred," said Marc Rotenberg, executive director of the Electronic Privacy Information Center, a privacy advocacy group.

And that makes it harder for courts to determine whether a certain digital surveillance method invokes Fourth Amendment protections against unreasonable searches.

In the cellular-tracking cases, some legal experts say that the Store Communications Act refers only to records of where a person has been, i.e. historical location data, but does not address live tracking.

Kevin Bankston, a lawyer for the Electronic Frontier Foundation, a privacy advocacy group that has filed briefs in the case in the Eastern District of New York, said the law did not speak to that use. James Orenstein, the magistrate in the New York case, reached the same conclusion, as did Judge Smith in Houston and James Bredar, a magistrate judge in the Federal District Court in Maryland.

Orin S. Kerr, a professor at the George Washington School of Law and a former trial attorney in the Justice Department specializing in computer law, said the major problem for prosecutors was Congress did not appear to have directly addressed the question of what standard prosecutors must meet to obtain cell-site information as it occurs.

"There's no easy answer," Mr. Kerr said. "The law is pretty uncertain here."

Absent a Congressional directive, he said, it is reasonable for magistrates to require prosecutors to meet the probable-cause standard.

Mr. Fishman of Catholic University said that such a requirement could hamper law enforcement's ability to act quickly because of the paperwork required to show probable cause. But Mr. Fishman said he also believed that the current law was unclear on the issue.

Judge Smith "has written a very, very persuasive opinion," Mr. Fishman said. "The government's argument has been based on some tenuous premises." He added that he sympathized with prosecutors' fears.

"Something that they've been able to use quite successfully and usefully is being taken away from them or made harder to get," Mr. Fishman said. "I'd be very, very frustrated."
 
So I suppose it won't be long before the government bans disposable phones that you payt cash for at convenience stores since they need to know where everybody is.
 
Sure it can be a great help to law enforcement. So can a search of someone's home. Get a warrant.
 
We are such a odd bunch. I heard on one of the Cable channels about 2 weeks ago about a family that was suing ON STAR. Some family member was car jacked I think maybe injured or killed. Now the family is suing even thought they never paid and bought the service ON STAR provides. They were too dumb to know they had to do that so I guess if they will there will be a big sticker someone in peoples vehicles telling them they must pay if they expect service. Damned if you do or don't. Oh yeah as a blanket statement most lawyers are greedy and dangerous as well as citizens.
 
Hmmm.... can the cell phones still be accurately tracked when the "location' function is off?

My cell phone allows me to turn off the location function. It is designed to, "allow the network to detect your position." Mine is turned off, of course, but does that affect the police's tracking ability?

I imagine that the phone can still be located (somewhat accurately) through triangulation during a phone call.

Anyone have the 4-1-1, yo?:scrutiny:
 
I have read that you must take the batteries out. JUst being on off does nothing to tracking system.:scrutiny:
 
Fly320s,

I think you're talking about two different technologies. The "location" thing that you can turn off is GPS location for e911 service; the phone itself knows its own position by using GPS just like any other mapping or location tool. The phone can then report its position voluntarily. Whether or not you shut this feature off, if you have a GPS-capable phone and you dial 911, the location information will be sent; all you have the option of shutting off is whether the phone will constantly update the cell provider with its current GPS location.

The technology that's being discussed here is, if I'm correct, a passive location technology, were the cell telco can locate the handset based solely on its emanations, and it works with phones that don't have the GPS capability. Whenever a cell phone is turned on, it's yammering to the local towers, so that the network knows where it is, so that an incoming call can be routed to the proper tower. It's that yammering they're counting on for this particular technology.

TWO POINTS=>

1. It may help locate a youth or a lost person... so cell phone tracking does have merits.

2. I don't believe it is technically possible to track a cell phone that is shut off as no signal is being processed!

This bears repeating, often and loudly.

Not that anyone is listening...

I can't get too excited about it. The gubmint already knows who I am, where I live & work, what vehicles I drive, how much money I make and where I spend it, and what firearms I own. What difference does it make that they know where my cellphone is?

If I wanted to do something illegal and avoid cellphone tracking, I'd just buy one of those disposable cells for cash.

Can't you just switch it off? Why do I need to remove the batteries?

Fly320s, how do I disable the "Location" function? Is that a user-accessible parameter?

I have the option of only allowing it to report locations for 911 calls. Whether or not it only reports then, or if emergency services can still remotely activate it, I dunno.

One case I do know of, however. One of my mother's co-worker's friends was found dead in the woods, of a heart attack. They only found him because of the signal on his cell phone.
 
If you can use the cell phone, the cell phone system (and therefore the cell phone company) knows, at a minimum, which cell it is in. Regardless of any settings on the phone.

In rural areas the cell size is larger and knowing what cell you are in would be pretty useless. In a very densely populated area, cells are smaller, and the phone may be in contact with more than one cell at a time. In that case, the position could be more precisely known and tracked.

Turning off the phone should be sufficient to "hide" it from the system. The phone must "communicate" with the system for the system to know where it is. Presumably, it stops transmitting when you turn it off. So unless your batteries run down while your phone is turned off, you're "safe."

Depends on how it's set up. Wouldn't be hard at all to have a system that apparently shuts off, but continues to transmit certain signals unknown to the user.

That's just scary. You don't care that they (might) have the ability to track you wherever you go?

I don't care only because there's nothing I can do about it, but I do understand and fully support the objection to that ability.

Do you know that the IRS can locate any bank accounts under your social security number with a few mouseclicks? And that they can locate any vehicles registered in your name just as easily? For example, if you file tax returns showing you made, I dunno, $30k-$50k, but have a yacht and an expensive car registered in your name, they'll suspect you haven't reported all your income and will most likely launch an audit. You'll have to show where you got the money for the yacht and Ferrari and why it wasn't reported on your tax return.

Your credit card purchases are also an open book. Even the supermarkets track purchases via your 'club card'. Without it you pay higher prices, which I'm not willing to do.

Our employment records, spending records, records of ownership of registered vehicles and firearms, etc., are all wide open to government examination. Ownership of real property is a public record. I don't like it a bit, but there's not a thing I, or you, can do about it. Unless you're willing to go completely 'underground', exist without credit cards, bank accounts and vehicles. Even being self-employed won't keep you out of the system. Your customers who are businesses are required to report any payments to you that equal or exceed $600, and in any event you'll be paid by checks you'll have to negotiate somehow.

I'm not sayin' it's right, only that resistance/avoidance is futile. :(

I do what I can to stay off the radar. I use a lot of cash and used a fake name for my supermarket "club card," not because I think they'll do something with the information but because it's none of their damn business what I buy. I realize we can't avoid all government intrusion, but it must be fought every step of the way, even the last step. Tracking you through your cell phone (for some people a very necessary item) must be fought as well.
 
That comment about sueing OnStar sounds nuts. I have their emergency service. I get several letters from them every year arond when the service is about to run out. No excuse there. You can even call them using the OnStar system to pay the bill even if it is expired. I did that last year.

In any given area code, there are many people who share the phone number 123-4567. Instead of just punching my number into the keypad, I ask the clerks to key my number in for me, just to see the look on their faces.

This came up in Enemies Foreign and Domestic, but I don't know if there are any phones that actually do this. Does anyone know?
 
I can't get BATFE to run a check on a gun recovered in a crack house to tell me its history. I can't get the Secret Service to care about the counterfeiting ring we've got going on because they only make $5 bills, and only in small lots on a home computer. I can't get INS to care about illegal immigrants smuggling meth. I can't get DEA to help us track where the "mexican meth" is coming from.

You know, after being a "goobermit" employee for 11 years, after some time in the Army, all I can say is that I wish I had the resources available that some people assume the government does have.

I work as an engineer for a major cellfone manufacturer, and there is MUCH confusion in this thread.

There are TWO TYPES of "locating methods" available for cellfone operators:
1. GPS-type ------These can be turned off by the cellfone owner/user thru the menu. They are also NOT available on all brands/models of cellfones.
2. Control channel type ------ All cellfones have TWO streams of data going back and forth between the fone and the network. One stream is the voice communication, the other is network related information related to the fone's location inside a particular cell and other parameters necessary for network operation. This form of location information can ONLY be defeated by leaving your fone powered down. Once the fone is powered up again, tho, the system once again 'records' your location, so there is no way to completely defeat this feature and still use the fone.

You need more tinfoil. No current cellfone works that way. (See my other post for details.)
