But the latest drone technology — mirroring technology that powers self-driving cars — has the power to transform everyday policing, just as it can transform package delivery, building inspections and military reconnaissance. Rather than spending tens of millions of dollars on large helicopters and pilots, even small police forces could operate tiny autonomous drones for a relative pittance.

That newfound automation, however, raises civil liberties concerns, especially as drones gain the power to track vehicles and people automatically. As the police use more drones, they could collect and store more video of life in the city, which could remove any expectation of privacy once you leave the home.
