How to hide from a drone - the subtle art of 'ghosting' in the age of surveillance

Drones of all sizes are being used by environmental advocates to monitor deforestation, by conservationists to track poachers, and by journalists and activists to document large protests. As a political sociologist who studies social movements and drones, I document a wide range of nonviolent and pro-social drone uses in my new book, "The Good Drone." I show that these efforts have the potential to democratize surveillance.
