Having working in the field for a few years, the amount of utterly irresponsible assholes would shock you. I was on a few hundred thousand hectare fire, and someone was flying their small personal aircraft over the area repeatedly. He was arrested when he landed at the nearest airport, but for a few hours all the helicopter support was grounded because of one jackass who wanted a better view.
My guess is it's an LAPD operator. The civilians stayed out of the restricted airspace. Some chud cop thinks the rules don't apply to him, so he flies a drone in an unauthorized zone. He manages to hit a firefighting plane. And the LAPD quickly sweeps the whole thing under the rug and blames it on a never-found civilian.
