Setting aside the paranoia and conspiracy theories surrounding drones, they are remarkably hard to shoot down. After all, drones have been deployed to honest-to-Flying Spaghetti Monster combat zones against fighters with military-grade weapons, tactics, and training.
Yes, drones have been shot down. Less than 5 of the earlier UAV variants were shot down in Kosovo using anti-aircraft weapons and shoulder-fired missile launchers. But when drones go down--infrequently-- it's usually because of a mechanical malfunction. Moreover, today's drones are better protected in terms of avionics (the part you need to disable)--standard hunting gear just ain't gonna do it.
Of course, this ignores the fact that shooting a moving aircraft at a distance of well over 600 feet with a legal firearm --ain't gonna happen. And let's not forget--gunloons aren't the brightest among us --can they distinguish between the Evvvvilll Gobbbeermint drone and the Piper Cub? And let us not forget that throwing lead into the air for no good reason has bad consequences
