The question of whether or not the FAA will go after the pointer aside, I am curious as to why you seemed to remain in the vicinity of the pointer and turned the camera back towards them several times? I'd have though it was wiser to get the heck out of there as quickly as possible.
I can imagine a laser being dangerous for the camera but could it cause damage to the drone that could bring the drone down? If so then pointing a laser at a drone in flight surely constitutes an attack on an aircraft in flight, doesn't it?
Of course if pointing a laser at a drone poses no risk of causing crash-causing-damage to the aircraft then maybe the FAA wont be bothered
