its not spying if they are in public, as long as you dont fly over them or do anything unsafe; photography wise your fully within the law to video tape someone on public property. being a stickler i know :P but its not spying if its known and allowed. in all seriousness tho as a hobby drone pilot seeing what someone is doing is always the last thing on my mind when im in the air with the goggles on.
