Federal Judge: Only Powered-Off Cell Phones Deserve Privacy Protections

By Chris Soghoian, Principal Technologist and Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 11:27am

A federal magistrate judge in New York recently ruled that cell phone location data deserves no protection under the Fourth Amendment and that accordingly, the government can engage in real-time location surveillance without a search warrant. In an opinion straight from the Twilight Zone, magistrate judge Gary Brown ruled two weeks ago that “cell phone users who fail to turn off their cell phones do not exhibit an expectation of privacy.”

The case in question involved a physician who the DEA believed had issued thousands of prescriptions for pain killers in exchange for cash. In March of this year, the DEA had obtained a warrant for his arrest, and,

What the Government Says When It Says Nothing

By Bennett Stein, ACLU Speech, Privacy and Technology Project at 1:36pm

On May 8, the ACLU released a slew of government documents obtained from the FBI, U.S. Attorneys' offices around the country, and the Justice Department's Criminal Division concerning the government's access to the contents of private electronic communications. The media has seized upon one of those documents, an undated memo titled, "Guidance for the Minimization of Text Messages over Dual-Function Cellular Telephones." This memo may show that the Criminal Division is doing nothing at all to avoid reading our text messages; it may show great procedures in place to safeguard the privacy our text messages; or, likely, it may have nothing to do with either of those predictions. The public does not know because the Justice Department put a large black box over every word following the header of the 15-page memo.

Justice Department Refuses to Release GPS Tracking Memos

By Catherine Crump, Staff Attorney, ACLU Speech, Privacy and Technology Project at 11:12am

Two key memos outlining the Justice Department’s views about when Americans can be surreptitiously tracked with GPS technology are being kept secret by the department despite a Freedom of Information Act lawsuit filed by the ACLU to force their release. The FBI’s general counsel discussed the existence of the two memos publicly last year, yet the Justice Department is refusing to release them without huge redactions. (You can see the heavily censored versions sent to the ACLU here and here, and our original FOIA request here.)

Mobile Phone Surveillance by the Numbers

By Chris Calabrese, Legislative Counsel, ACLU Washington Legislative Office at 10:56am

Wow.  Sometimes one word says it all.  The New York Times reports that in response to letters from Rep. Edward Markey (D-MA) and Rep. Joe Barton (R-TX), mobile phone providers disclosed that they received approximately 1.3 million law enforcement requests for customer records last year alone. What an extraordinary number: more than a million accounts subject to at least some level of law enforcement investigation just in 2011. As we have discussed elsewhere, beyond what is reported by carriers in these letters, there is absolutely no reporting or tracking regarding how these numbers are handled.  

Even more amazing, as you dig into the article and read the underlying letters it becomes clear that this is actually a vast undercount of the number of Americans who have been affected by this tracking.  Sprint disclosed that it received approximately 500,000 subpoenas in 2011 (a subpoena is a written request for information from law enforcement that isn’t reviewed by a judge) and that “each subpoena typically requested subscriber information on multiple subscribers.” In addition, several carriers disclosed that they sometimes provide all the information from a particular cell tower or particular area.   Metro PCS for example charges:

$50 for Cell Tower Dump per tower for a 2 hour period
$100 for an Area Dump (if you know the location but do not know the cell towers that affect the area) for a maximum of 2 cell towers for a 2 hour period per cell tower search

Everyone whose phone has been used by a particular cell tower over a particular time period—likely hundreds or thousands of people—could have their data examined by investigators.  And these dragnet data requests are on the rise.  Verizon estimates that over the last 5 years it has seen an average increase of 15% annually, and T-Mobile reported increases of approximately 12%-16%.  This has also led to at least some possible abuse; T-Mobile disclosed that in the last three years it has referred two inappropriate law enforcement requests to the FBI. 

What We Know About License Plate Tracking, What We Don't, And Our Plan to Find Out More

By Kade Crockford, Director, ACLU of Massachusetts Technology for Liberty Project at 12:31pm

Today the ACLU is launching a nationwide effort to find out more about automatic license plate readers (ALPR). By snapping photographs of each license plate they encounter—up to three thousand per minute—and retaining records of who was where when, license plate readers are fundamentally threatening our freedom on the open road.

A Creeping Private-Sector “Checkpoint Society”—and a Small Step to Protect Your Privacy

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 4:03pm

I was at a Target store recently and threw a bottle of wine in my cart to bring as a gift to a party. Later, when I got to the register, the cashier asked to see my ID. That in itself was silly, because it’s safe to say I’m a few years past the point where anyone might mistake me for someone under 21. But whatever; alcohol age-enforcement has gotten bureaucratic beyond all reason.

I held the ID up for her to see. Before I could react, she took my license from my fingers, held it up to a scanner, and BEEP!

Police “Google Searches” Through Our Location History? No Thanks

By Kade Crockford, Director, ACLU of Massachusetts Technology for Liberty Project at 3:24pm

Imagine a searchable database that would enable police or federal agents to instantly track everywhere you’ve ever driven in your car, like a “Google search” of your location over a period of months or even years. According to a law enforcement data manager speaking at a 2010 National Institute of Justice conference, that’s where the government is headed.

ACLU testimony in hearing today on location tracking

Supreme Court GPS Ruling: Bringing the 4th Amendment Into the 21st Century

By Catherine Crump, Staff Attorney, ACLU Speech, Privacy and Technology Project at 2:05pm

On Monday the Supreme Court issued a landmark decision protecting privacy in the digital age. In U.S. v. Jones, a unanimous Supreme Court held that the police and FBI violated the Fourth Amendment when they attached a GPS device to Antoine Jones’s car and tracked his movements for 28 days. While the case turned on the fact that the government physically placed a GPS device on Mr. Jones’s car, the implications are far broader. A majority of the justices acknowledged that advancing technology, like cell phone tracking, gives the government unprecedented ability to collect, store, and analyze an enormous amount of information about our private lives.

ACLU in Court Today Arguing that GPS Tracking Requires a Warrant

By Catherine Crump, Staff Attorney, ACLU Speech, Privacy and Technology Project at 9:59am

Should law enforcement agents have to obtain a warrant based on probable cause to attach a GPS tracker to a vehicle and track its movements? Several months ago we asked the Third Circuit Court of Appeals to consider our argument that they should (you can read our amicus brief here). Today, we will be in court arguing that point in the case of Harry, Mark, and Michael Katzin.
