EFF: “With major protests in the news again, we decided it’s time to update our cell phone guide for protestors. A lot has changed since we last published this report in 2011, for better and for worse. On the one hand, we’ve learned more about the massive volume of law enforcement requests for cell phone—ranging from location information to actual content—and widespread use of dedicated cell phone surveillance technologies. On the other hand, strong Supreme Court opinions have eliminated any ambiguity about the unconstitutionality of warrantless searches of phones incident to arrest, and a growing national consensus says location data, too, is private. Protesters want to be able to communicate, to document the protests, and to share photos and video with the world. So they’ll be carrying phones, and they’ll face a complex set of considerations about the privacy of the data those phones hold. We hope this guide can help answer some questions about how to best protect that data, and what rights protesters have in the face of police demands.”
