So basically the British lawmakers' train of thought is as follows:
Drones were flown at Gatwick by some hooligans who knew they were doing something illegal but still opted to do so. And therefore the best way to combat them is to make all OTHER operators of drones who were flying them responsibly and outside of airports to obtain a drone pilot's license and a registration for their drones.
For the first time in my life since I was 11 months old, I'm speechless.
