Twitter Subpoenas Chill Free Speech; Latest Example is in San Francisco

By Linda Lye, Staff Attorney, ACLU of Northern California at 4:52pm
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 unlawful assembly during a Columbus Day demonstration last year. They had been active on Twitter but disabled their accounts after the protest.

Court Ruling Gives FBI Too Much Leeway on Surveillance Technology

Court Ruling Gives FBI Too Much Leeway on Surveillance Technology

By Linda Lye, Staff Attorney, ACLU of Northern California at 5:09pm

Today, a federal district judge in Arizona issued a very disappointing decision concerning the government’s obligations to be candid with courts about new technologies they are seeking a warrant to use.

The case involves Daniel Rigmaiden, who is being criminally prosecuted for an alleged electronic tax fraud scheme. The government used a surveillance device known as a stingray to locate Mr. Rigmaiden. A stingray operates by simulating a cell tower and tricking all wireless devices on the same network in the immediate vicinity to communicate with it, as though it were the carrier’s cell tower. In order to locate a suspect, a stingray scoops up information not only of the suspect, but all third parties on the same network in the area. This means that when the government uses a stingray to conduct a search, it is searching not only the suspect, but also tens or hundreds of third parties who have nothing to do with the matter. When the FBI sought court permission to use the device to locate Mr. Rigmaiden, it didn’t explain the full reach of stingrays to the court.

The ACLU and the Electronic Frontier Foundation filed an amicus brief arguing that when the government wants to use
