Apparently the Trump shooter flew his drone over the site a couple of hours before he fired. https://www.wsj.com/politics/nation...hours-before-attempted-assassination-2d0e2e1aALL Boogymen have Drones now just ask the Anti-Drone lobby!
He also owned a car, computer, phone, and probably a bag of peanut M&M's.(doesnt everybody).
Exactly how does the fact that he was a DJI customer change any facts or make him more prevalent to assisinate a presidential candidate?
