Just a thought with regard to a post a few days back when a pilot, in a public park was verbally 'abused' by a couple of dig walkers about 'surviallnce' in a public place. Maybe an idea to help mitigate any issues with members of the public would be to buy a small plastic, self standing sign(s) that the pilot could place strategically at entrances to public places, warning them of 'UAVs flying above' or something like that. Maybe another sign 'granted land owner permission' for when pilots use private land (with prior permission of course), so if anyone has issues etc etc, they see the sign first...so it gives the impression of the pilot credibility and not just a peeping tom. I see them on ebay. Just an idea. And don't use the word drone or UAV for your P3, as to the general public this conjures up a Predator drone, hellfire missiles. PRAS (remote piloted aircraft system) seems more professional, more grown up and might help the public to understand our hobby a bit more.
