In a disturbing trend that can have a chilling effect on free speech, law enforcement agencies around the country are seeking wide-ranging information about the social networking activity of political activists. The San Francisco District Attorney recently issued subpoenas to Twitter for tweets by two political protesters, Lauren Smith and Robert Donohoe, who had been charged with rioting and unla...

The next time a cop sees a picture of you, that picture may not have been taken by a person at all. Unmanned flying drones can allow their operators to remotely - and cheaply - monitor and record individuals, groups, or locations. These drones pose significant threats to privacy when police can use them to peer into homes or track an individual's actions from afar. While law enforcement agencies a... Read More

Buried on the Board of Supervisor's 66-item agenda for its December 4, 2012 hearing was a surprising request by the Alameda County Sheriff's Office for approval to "apply for, accept and administer" funds from the California Emergency Management Agency (Cal-EMA) to buy a drone.This was very troubling for a number of reasons.The Sheriff to date has not been forthcoming about his intentions and act...

The company recently announced a partnership with information broker Datalogix, which operates many of the loyalty card programs we use to get a discount at stores like CVS. The partnership — one of Facebook's three new advertising programs —allows Facebook to gauge the effectiveness of its ads by learning about the offline pu... Read More

This morning, 26 individuals and organizations including the ACLU of California sent an open letter to new Yahoo! CEO Marissa Mayer asking her to add HTTPS security to Yahoo! Mail. Without secure connections, the email sent and received by Yahoo! users around the world — from dissidents living under repressive regimes to Americans communicating about sensitive topics — is vulnerable to interceptio...

In mid-October, the Alameda County Sheriff's Office revealed that it was seeking funds to purchase a drone to engage in unspecified unmanned aerial surveillance. The ACLU of Northern California immediately sent a Public Records Act request seeking answers to three basic questions: 1) Are drones really necessary in our community; 2) How much will they cost to acquire, operate, and maintain; and 3) ...

The ACLU and Electronic Frontier Foundation have filed an amicus brief in what will be the first case in the country to address the constitutional implications of a so-called "stingray," a little known device that can be used to track a suspect's location and engage in other types of surveillance. We argue that if the government wants to use invasive surveillance technology like this, it must expl... Read More

Shortly before next week's one-year anniversary of the Oakland Police Department's brutal crackdown on Occupy Oakland, Alameda County Sheriff Greg Ahern announced that he was seeking funds to purchase a drone to engage in unspecified unmanned aerial surveillance. One of the many unfortunate lessons of OPD's Occupy crackdown is that when law enforcement has powerful and dangerous tools in its arsen... Read More

Late last week, Gawker's Adrian Chen "unmasked" Violentacrez, a notorious "troll" on the content aggregator Reddit. Violentacrez is a remarkably unsympathetic figure; as the article put it, his "specialty is distributing images of scantily-clad underage girls," and he "also issued an unending fountain of racism, porn, gore, misogyny, incest, and exotic abominations yet unnamed." Yet while the stor... Read More

When Apple expanded the availability of its FaceTime videochat app to cell networks, AT&T responded by announcing that only iPhone and iPad users with a high-priced "Mobile Share" data plan would get to use the app on its network. In other words, ordinary AT&T customers—many of whom pay the carrier both for their mobile device and for the data they use—have been cut off from an easy way to... Read More

The Location Privacy Act of 2012 was intended to ensure the privacy of Californians by requiring law enforcement and other government entities to get a search warrant before obtaining information about the location of an electronic device. As a result, it garnered broad bipartisan support in its passage through the California legislature. Unfortunately, Governor Brown ignored this support and chos... Read More

Last week, LA Weekly ran a story indicating that the Los Angeles Police Department is using a device called a "Stingray" to track cell phones. Law enforcement seems to think that because these devices can track cell phones without going to the trouble of even interacting with mobile carriers, they don't need a search warrant. Please tell Governor Brown to sign the Location Privacy Act of 2012 into... Read More
