"The gunman who tried to kill Donald Trump was able to fly a drone and get aerial footage of the western Pennsylvania fairgrounds shortly before the former president was set to speak there, law-enforcement officials briefed on the matter said, further underscoring the stunning security lapses ahead of Trump’s near assassination. Thomas Matthew Crooks flew the drone on a programmed flight path earlier in the day on July 13 to scour the Butler Farm Show grounds ahead of Trump’s ill-fated rally, the officials said. The predetermined path, the officials added, suggests Crooks flew the drone more than once as he researched and scoped out the event site." - wsj.com
