We'll have heard of drones being used to smuggle drugs etc into prisons, there have been near misses with aircraft. It seems obvious that ISIS or a similar terrorist organisation may attempt a strike on, say, a Buckingham Palace garden party, or another high profile target using a variety of nasty agents. I cannot believe how there are so few regulations nor prosecutions. Surely, as a minimum, they should be licenced to named, traceable individuals, and drone free zones rigoursly enforced. I hope I am wrong in worrying.
