New documents from the FBI and U.S. Attorneys’ offices paint a troubling picture of the government’s email surveillance practices. Not only does the FBI claim it can read emails and other electronic communications without a warrant—even after a federal appeals court ruled that doing so violates the Fourth Amendment—but the documents strongly suggest that different U.S. Attorneys’ offices around the country are applying conflicting standards to access communications content (you can see the documents here).

Last month, in response to a Freedom of Information Act request, the ACLU received IRS documents indicating that the agency’s criminal investigative arm doesn’t always get a warrant to read Americans’ emails. Today we are releasing these additional documents from other federal law enforcement agencies, reinforcing the urgent need for Congress to protect our privacy by updating the laws that cover electronic communications.

The FBI and Electronic Communications: Where’s the Warrant?

The documents we received from the FBI don’t flat out tell us whether FBI agents always get warrants, but they strongly suggest that they don’t.

In 2010, the Sixth Circuit Court of Appeals decided in United States v. Warshak that the government must obtain a probable cause warrant before compelling email providers to turn over messages to law enforcement. But that decision only applies in the four states covered by the Sixth Circuit, so we filed our FOIA request to find out whether the FBI

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,

Last year in Norristown, Pa., Lakisha Briggs' boyfriend physically assaulted her, and the police arrested him. But in a cruel turn of events...

Eye tracking technology received new attention recently due to its inclusion in the Samsung Galaxy IV phone, where it can (with mixed results, according to reviewers) let users scroll the screen with their eyes or dim the screen when they look away. Clearly this is a technology that has the potential for a lot of clever applications. But what are the privacy implications?

Eye tracking for research was used for over a century before computers (see the quick history outlined in this article). The earliest research, in the 19^th century, actually involved direct mechanical contact with the cornea. Already by 1898, researchers were discovering some really cool phenomena of the human brain. Motion pictures were applied to the problem as early as 1905, and the first head-mounted eye-tracker was developed in 1948, which freed study subjects from having to keep their heads still. In the mid-1970s the first remote trackers were developed that were truly unobtrusive to the subject. By then, research and writing based on eye tracking was booming, not only on the part of psychologists but also the military.
