Sorry HMG, the horse has bolted a long time ago
The ner-do-wells that use then for :-
- Dropping goodies to crims in jail
- Voyeurism
- Closing Airports
Will have them already and like their cars and TV's won't have licenses, insurance or even and documentation to show who bought the thing in a different country.
They will give anyone asking about the drone the finger and if that does not work then proper violence will be used.
As has been said, I'd love to be legally able to shoot the effing things down on sight. Why? One regularly buzzes my sisters house and obviously tries to get piccies of her naked. Everyone knows who does it but they are part of a family that you don't mess with. The Plod won't do anything naturally. Perhaps if my sister had a little girl then they might help...
