Bob,
I hear what you are saying but drones also bring persistence - so whilst they may have been conceived as a way of keeping people out of harm's way, perhaps that's not exactly where they sit anymore.
Also, it's quite a statement to make isn't it? We're watching you and we know you don't like it - but we've got a little toy you can't see knocking around for when you get a little tense. Perfect.
Incidentally - to the 'how did they do it?' camp, sounds like a very basic intercept onto a TIDS track to me. No need to have anything radiating for that.
