I did come up with a not-altogether-unserious proposal for mitigating internal misuse of arial drones by mobilizing our distributed civilian expertise and firepower: Hunt drones. In peacetime nobody would buy in, but maybe the virtues of the idea are a little more obvious now.
Sell hunting licenses for them. A downed drone becomes the property of the hunter. Within city limits, allow birdshot or launched nets only; a few other minor restrictions seem reasonable. Damage or injury caused by the crash is the responsibility of the most recent controller of the drone. Sorry, Amazon; yours are targets too.
Yes, I know nighttime hunting wouldn't be popular, and the machines are useful in finding out what's going on in disasters.
