So you think punishing or restricting the majority will make any difference to future instances like this?
I think having in place sensible controls on devices / machines which can be used in disruptive and dangerous ways will restrict this type of incident in the future. I get that this is a hobby for some people and I understand and appreciate that, however that doesn't mean that it shouldn't be regulated. My hobby happens to be very heavily policed and regulated, and entirely rightly. I enjoy cars and driving but that doesn't mean I should be able to drive what I want, where I want in any manner I want. There are rules and laws and restrictions and licenses for everyone who wants to drive a car, regardless of their intent. Does it stop people using cars as weapons against people and infrastructure? No, but it massively reduces the possibility. Perhaps you think that is unfair?
Or do you perhaps think it's possible to unilaterally ban the manufacture, sale and use of drones completely, remove all the internet content on how to bypass drone restrictions, or modify a drone for longer endurance, and get everyone to forget completely how to build, modify or fly a drone?
Congratulations, reductio ad absurdum.
