Drone technology is advancing at an impressive pace. I think we're going to see some interesting (and terrifying) applications.
For example: Add some face detection software, then change the payload to a laser dazzler and pepper spray cartridge. Now you have a drone that can temporarily incapacitate people. When these get cheaper (say $100 per unit), a police department could buy a swarm of 1,000 for $100k. Whenever a riot breaks out, just unleash the drones (geofenced to the desired area). Instant crowd control.

Like I said, interesting and terrifying.
