Court rulings unsealed last week in Washington show for the first time a behind-the-scenes legal battle over when the government should have to tell you that it's tracking your location and reading your email. These documents—which came to light only as the public learned more about the government's controversial investigation of Fox News journalist James Rosen—reveal significant new details about the government's obligation to provide notice, after the fact, when it obtains geolocation data or obtains stored email messages. Indeed, the court orders bring to light a striking contrast: federal prosecutors in Washington routinely provide notice to individuals they track using cell-phone geolocation data, even if that notice is delayed, yet the government strenuously resists giving any notice to individuals when searching and reading their emails.

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,

A few years ago, one of our ACLU state affiliates received a request for help from a man who had set up a marijuana grow operation in his home. He was apparently quite proud of what he built, because he bragged about it not only to his friends, but also to his Facebook “Friends.” Unfortunately, one of his Friends was Friends with a police officer a thousand miles away in Florida. That police officer called up his colleagues in

Recently, Dr. James Watson filed an amicus brief opposing gene patents in our lawsuit challenging the patents on two human genes associated with hereditary breast and ovarian cancer. Dr. Watson, along with Francis Crick, identified DNA’s ability to create life through its double helical structure and its information-coding sequences in 1953. His brief explains why, from the perspective of a scientist whose work laid the foundation for all genetic research, gene patenting is “lunacy.”
