Back in the mid 90s, I sketched the rough outline of an action-adventure novel, centered around an assassination attempt using a specialized miniature cruise missile. Actually, sort of a cruise missile / drone hybrid.
I didn't actually write it, for a variety of reasons: didn't want to give people ideas, couldn't figure a way for the hero to foil the plot, had other priorities in life, lack novel-writing aptitude, that sort of thing. But the idea kind of stuck with me, technology has improved to the point that such an attack would be much more plausible now than it would have been at the time, and I have a couple of variants on the drawing board. And I still can't figure a way for the hero to foil the plot at the last moment.
And now... someone's tried to blow up a South American dictator (who recently showed signs of political unreliability), apparently using toy aircraft laden with explosives (via). A crude attempt, but they'll surely get more sophisticated in the future.
No, restricting technology isn't the answer. The genie is well and truly out of the bottle, and much of modern life depends on the technologies that will soon enable autonomous hunter-seeker missiles.
(Yes, there are potentially ways to protect point targets, without necessarily putting them behind armored domes. I don't feel like mentioning them here. OK, so I'll suggest a 12-gauge DIVAD.)
Update: ... Or, the incident may have been a Reichstag fire, possibly without the trouble of having an actual fire. Especially if (as is rumored) all the injuries were caused by a stampede, with none resulting from the purported explosion.
Update to the update: I'm not sure where I'd encountered this Orwell quote within the last few days, but it seems relevant.
Early in life I have noticed that no event is ever correctly reported in a newspaper, but in Spain, for the first time, I saw newspaper reports which did not bear any relation to the facts, not even the relationship which is implied in an ordinary lie. I saw great battles reported where there had been no fighting, and complete silence where hundreds of men had been killed. I saw troops who had fought bravely denounced as cowards and traitors, and others who had never seen a shot fired hailed as the heroes of imaginary victories; and I saw newspapers in London retailing these lies and eager intellectuals building emotional superstructures over events that had never happened. I saw, in fact, history being written not in terms of what happened but of what ought to have happened according to various ‘party lines’.
So, perhaps a random domestic accident that made a loud noise is being reported as an organized assassination attempt, soldiers trampled in the rush to get away are being reported as heroes, and it will all make a handy pretext for exterminating some political opponents?
