There is this approach of using airplanes taking pictures every second. When a crime like drive by shooting and putting a bomb in a bin is commited, this technology allows the investigators to rewind time and fast forward to discover where the car/person come from/went and eventually catch it. It was used to figure out location of drug cartel head quarters. This wouldn't be efficient against a swarm of drone attack though, as they can be operated remotely from miles away.
