American Civil Liberties Union

Can using privacy-enhancing tools (such as Tor or a Virtual Private Network) actually expose you to warrantless surveillance by the National Security Agency? This week, the ACLU sent off four FOIA requests to federal agencies in order to try and answer this question.

To understand why we think that may be the case, we have to go back to the passage of the FISA Amendments Act (FAA) in 2008. That act was not a high-point for civil liberties or the rule of law. It included a provision giving immunity to the telecom companies that violated the law by assisting the NSA with its warrantless wiretapping program. Although the get-out-of-jail-free card given to the phone companies is the most well-known aspect to the FAA, there is much more to the law, and many other things that give privacy advocates reason to worry.

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.

In the digital age that we live in today, we are constantly exposing our personal information online. From using cell phones and GPS devices to online shopping and sending e-mail, the things we do and say online leave behind ever-growing trails of personal information. The ACLU believes that Americans shouldn’t have to choose between using new technology and keeping control of your private information. Each week, we feature some of the most interesting news related to technology and civil liberties that we’ve spotted from the previous week.

A few days ago, we highlighted the drastic privacy implications of new guidelines issued to govern data-mining by the National Counterterrorism Center (“NCTC”). Yesterday, we testified to Congress about the problems with the guidelines, and we filed three Freedom of Information Act (“FOIA”) requests to learn more about how the guidelines will affect the privacy of millions of Americans.
