I'm an avid shooter, gun owner and a Law Enforcement Firearms Instructor for more than 37 years, and I agree with your assessment 100%.
It's good to know that they charged him with the "prohibited/illegal use of a firearm" as well as any civil authority matters that may arise from this incident. The "shooter" in this case isn't too bright . He may also lose his right to possess or purchase firearms or ammunition for up to five years.
On another note, I totally disagree with the writer of that article when he says "An angry Long Island man pulled a Clint Eastwood on a drone that was hovering over his St. James property." That is such a ridiculous statement to make, because Clint Eastwood would not do such a thing, and to assert otherwise is just irresponsible.
