Just what photos are you taking with your mothers Nikon Coolpix?
I find it interesting that you know that you can "be able to distinguish a man from a woman at even 1000 feet." and feel that you need to look up the laws regarding extreme telephoto lenses, as well as researching cameras to take high quality images, 40MP camera phone.. etc.
I also find it interesting that you infer that somebody (who probably has a fairly/extremely wide angle lens, as is usual with multi-rotors) had a obvious intent to take photos of the property and anything on it. Not projecting at all are we?
