I agree with Doors2Manual. Your comments seem to be more motivated by your feelings regarding the hunt itself than with aviation. It is far too early for such conclusions.
Overflying a football field is not illegal even if it is for an entire game provided you stick to the rule of the air.
The issue remains on the ground, what happened exactly, why was the engine on, who made which moves, and I think it all will have happened in seconds. So we ll see what comes out...
