If It’s Reasonable in Denver: Lessons in Location Tracking from Colorado

By Allie Bohm, Advocacy & Policy Strategist, ACLU at 12:00am

 

In April, ACLU of Colorado filed public records requests seeking to learn about their local law enforcement agencies’ policies, procedures, and practices for tracking cell phones, bringing the total count of ACLU-filed cell phone location tracking public records requests to over 400. (We’ve written about what we’ve learned nationwide here, here, here, here, and here, and our findings were featured in a front page story in the New York Times in April). What Colorado learned is particularly interesting because a remarkable number of law enforcement agencies in Colorado are getting probable cause warrants before tracking cell phone location information—Arvada, Boulder, Colorado Springs, Denver, and El Paso County always get warrants in investigative circumstances—and because Denver’s practices pretty much follow existing legislative proposals, proving these bills totally workable.

A Glimpse at the World of Digital Forensics

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 5:33pm

A gathering of cyber-crime specialists in Massachusetts last week provided a glimpse into the tactics used by prosecutors and police to access digital data. Kade Crockford of the ACLU of Massachusetts has done a nice writeup of the conference. As she points out, the event was closed to the press and the public, but the schedule of events was posted online, and included sessions with titles such as:

D.C. Judge: Government Doesn't Need a Warrant to Demand Cell Phone Location Information

By Chris Conley, Technology and Civil Liberties Fellow, ACLU of Northern California at 10:39am

Can the government demand location information records from your carrier without a warrant? Unfortunately, a D.C. District Court judge thinks so.

Documents Obtained by ACLU Shed Light on Other Telecom Surveillance Techniques

By Allie Bohm, Advocacy & Policy Strategist, ACLU at 9:57am

For the past year, the ACLU has been gathering information on local law enforcement agencies’ use of cell phone location tracking. (We’ve written about what we’ve learned here, here, here, here, and here.) In addition to everything we’ve discovered about location tracking itself, we’ve also learned about a number of other techniques law enforcement and the telcos can use when they work together. Sometimes the information came to light because, as with this telecom data retention chart, the information on the other techniques was mingled with the information on cell phone location tracking. Sometimes it was because law enforcement agencies misunderstood our public records requests and sent us everything they had related to telephones.

New Public Safety Broadband Network: Tool For A Domestic Secret Police?

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 6:19pm

Police in Tampa used smartphones and tablets to spy on protesters at the Republican National Convention, according to a report today from the National Journal.

Smartphones have proven to be an excellent tool for empowering individuals faced with sometimes unprofessional or abusive law enforcement officers, thanks to their built-in cameras and the constitutional right to record the police. But they also allow the police, according to the article, to blend in and transmit live video of protesters:

Friday Links Roundup

Here are some links that have caught our eye recently:

The FBI’s “Next Generation Identification” biometrics database is starting to plan for the inclusion of iris scans. Iris scans raise more issues than some other biometrics (such as fingerprints) because they can be used at a distance without a subject’s participation, permission, or even knowledge. Hand-held iris scanners are being sold to police around the country for identification uses. We were assured in a meeting with the FBI last year that biometric scans in situations such as traffic stops would not be used to enroll individuals into the database, just to check their identity.

Cell Phone Censorship in San Francisco?

By Rebecca Farmer, ACLU of Northern California at 5:15pm

Pop quiz: where did a government agency shut down cell service yesterday to disrupt a political protest? Syria? London? Nope. San Francisco.

The answer may seem surprising, but that’s exactly what happened yesterday evening. The Bay Area Rapid Transit (BART) asked wireless providers to halt service in four stations in San Francisco to prevent protestors from communicating with each other. The action came after BART notified riders that there might be demonstrations in the city.

Friday Links Roundup

The New York Times and Propublica jointly published an editorial last week entitled, “That’s Not My Phone, It’s My Tracker.” The authors review the sorry state of cell phone location privacy, raise and dismiss privacy-protecting options such as regularly removing the battery, or living without a phone, and conclude that what we should fight back linguistically at least, by calling these devices “trackers” rather than phones.

The Government, Privacy, and Companies (The Ones We Pay and the Ones We Don’t)

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 5:18pm

Privacy researcher Chris Soghoian gave a very nice talk at TEDx recently on “Why Google Won’t Protect You From Big Brother.” He provides a cogent overview and some useful perspective on the relationship between companies and the government, which is something we at the ACLU have been concerned about since our 2004 report on the Surveillance Industrial Complex, and before.

Email, Companies and Social Norms

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 10:51am

I wanted to make note of an interesting anomaly in a new survey that looks at Americans’ attitudes toward the privacy issues implicated by the use of mobile phones to pay for things (instead of cash or a credit card).

The survey (which is online here and is summarized by the New York Times here) finds that Americans react very negatively to the kinds of privacy invasions that mobile payments can bring.
