What the father needed was a tractor beam (a la Star Wars) to pull that sucker down. Then he could have checked out the pics. This is a tough one.
If the drone flew as low as claimed....the anti-aircraft artillery comes out.
I think what got him in trouble was threatening to pull his pistol on the guys who were coming to get the drone. Too bad he didn't pull out the SIM card so it could be examined.
The evidence is on that card.
