There are currently very clear rules on the non-commercial use of drones, aka small Unmanned Aircraft Systems (Commercial sUAS operations are handled under other rules). For example, stay under 400 feet, generally not within the vicinity of an airport, no closer than 500 feet of non-participating people and structures, maintain visual contact with unaided eye other than eye glasses and sun glasses. (I know I’m simplifying some of the rules, so bear with me on this
I agree there is little value to enforcement. There just aren’t enough FAA “police”. And, the local police aren’t always keen on enforcing FAA rules I’m not even sure local police have jurisdiction in the air. There is a long-standing ruling that local laws cannot regulate the airspace.
So, that leaves placing blame when something bad happens. If I’ve properly registered myself as an operator and properly labeled my sUAS and then I impact an aircraft or fall out of the sky onto people, then there is a record of who to arrest. I realize this whole scenario depends on someone labeling their sUAS before doing something illegal.
