I seem to recall some discussion about your military service. What is the distance you think you could put a round on a human sized target with an AR pattern rifle? Now, add enhanced optics. Now add a bipod or similar to keep the rifle steady. With a .308 or larger round, probably longer distances?
Now, I know there are FAA no drone areas around USSS monitored events and I know that the firmware will stop a drone from entering such a place but I'm not sure how well you can override that sort of thing. I think even the PRC manufacturer DJIA wouldn't want to get on the bad side of the FAA and FCC so they would comply.
Now you know that Trump likes to go to certain places owned by his cronies that don't mind so much if he stiffs them (as he surely will) and you have the ability to stage a device at such a place.
Go ahead and second guess the professionals because that's how your kind gets theirs back for being trapped in marginal lives.
