 Some of the attendees at a town hall meeting on drones at Bethesda Chevy Chase High School had suggestions for ways the camera-carrying drones could be used. Montgomery County Police Captain Jason Kokinos did emphasize drones respond to calls. They're not used as surveillance. If you are having a gathering at your residence, you're not going to have to worry about a police drone coming by. If it's a little too noisy, a police officer is going to come knock on your door.
