A confrontation over a drone flying above beachgoers ended with damaged equipment, a man behind bars and lingering questions over the line between public air space and personal space.
Sounds like they have no regs in teh US. In Canada drones can't legally be flown within 5 km of any built up area, so you have to be well out in the wild to fly one without a permit. Also can't be flown over festivals or forest fires or airports of course.
