On Wednesday, January 7, a federal immigration officer shot and killed 37-year-old Renee Nicole Good as she attempted to drive away from the scene of an immigration enforcement action in a Minneapolis, Minnesota, neighborhood. Protests condemning the shooting—and the Trump administration's brutish immigration agenda more broadly—sparked almost immediately after news of Good's killing surfaced. If you're going to join any protests, as is your right under the First Amendment, you need to think beyond your physical well-being to your digital security, too. Two key elements of digital surveillance should be top of mind for protestors. In that light, you should assume that any digital evidence that you were at or near a protest could be used against you.
