Find out here. Are your local or state police using drones? Which ones? How many? At what cost? For what purpose? Do they have rules for preventing abuses? MuckRock.com is a useful new open government webtool to help you answer these questions. It works with grassroots people to submit local public records requests to uncover agencies using or planning to use drones, then it enters the findings in a free, online Drone Census database that it is building, in partnership with the Electronic Frontier Foundation. MuckRock lets us keep watch on those who’re watching us.
