Be it operating a UAV out of plain view looking in on people, or hiding in the bushes with a gun aimed at taking down a spy, the whole anonymity factor to me seems to fuel the privacy concerns.
I was filming some of my kids' water activities from a hover point out over the lake they were on this past weekend. Like many, I enjoy the unique perspectives that aerial photography allows. I was later told by an older kid that was there that a supervisor of the activities said that what I was doing was illegal because I didn't have all of the kids permission to be photographed. I guess it is something about a flying camera that is perceived differently than half a dozen parents holding up iPhones, camcorders, or DSLRs.
I wonder if the young 20-something had any idea about the 20-year felony for taking down an aircraft when he was spraying water towards my
P4P with the water hose meant for the kids activity area .
