Discharging a shot gun near airports, neighborhoods, city limits, etc is SUPER illegal and because of the noise and relativly short distance (camera on drone can capture you) its super easy to get busted. Range of a shot gun is extremely paltry and you could end up hurting someone else with the shot.
We live in a police state so anyone acting like a free person has something to fear from our nanny police state. Our police state is so massive that it is rare when the people can stand up against it (remember FAA, FCC, DEA beurocrats are not elected officials - they create laws and "regulations" that congress rarely votes on, they do it from some back office like little dictators or monarchs). Once in a blue moon someone will go through the personal pain and sacrafice (remember there is no pain or sacrafice for the bearucrat writing police) to bring the regulation to the supreme court but its rare and the beaurcrat has little to fear.
There are things in the work with Trump administration to make these people MUCH easier to fire and to SUE - such as if the FAA creates some onerous policy for me to use my own property I can sue that guy personally and attach his entire net worth, take his kids 529 plan etc. I hope this becomes law because you will see alot of policy recalled and alot of firings.
For instance the FAA has made it virtually cost prohibitive for any serious recreational piloting through forced annual inspections by a "qualified person" (and of course getting that qualified persons status requires writing LARGE checks to the FAA designated persons), forced medicals, outrageously expensive examination fees and on and on. All so I can fly my own personal property.
Anyways I digress, I dont really want to get on here to talk about law because until we get enough congressmen in and a stronger president that will start disolving woodrow willsons little fiefdom then there is not much to do on the average citizens end. But I will tell you I wont table my academic endevors because of a bearucrat, especially in a state where its extremely difficult for the feds to operate.
