One exceptional day he seemed to be coordinating receipt of some large shipment, and he started freaking out about some truck driver not being where he was supposed to be who apparently had a tail to monitor his whereabouts.
Over the phone with the tail, quite loudly despite being on public display, he instructed the tail to "deploy the kite". Once deployed, he monitored a video+audio feed on his laptop from what must have been a kite surveillance drone. From the feed he seemed to discover the driver was on the phone arguing with his wife, and apparently this was the reason for pulling over.
Based on this experience I'm under the impression gangs are definitely already using drones. You probably don't hear much about it, because they're being successful.
