Last week, privacy attorney Grayson Barber brought her “drone” to CITP in order to do a demo at her talk, “Drones Are Like Flying Computers.” Grayson discussed the many serious legal issues raised by drones (you can watch the video of her presentation here). But her drone takes great video, so I couldn’t resist making…
