Someone briefly touched on it up above. I'm not Part 107 Certified, but I am a responsible pilot. I notify airports if I'm within 5 miles, stay under 400 feet (unless next to a tall structure), and don't fly over crowds. And I generally just try to be smart about it. However, I've seen videos of police trying to confiscate someone's drone simply because of a neighbor's complaint. A large percentage of the population doesn't view drones in a very positive light. I don't want to get in a situation where I did nothing wrong, but still risk getting a citation or my drone confiscated simply because of someone who is paranoid. If they can ID drones remotely, that just ups the chances of that happening. And I know some people will say, "If you did nothing wrong, you have nothing to worry about." Sadly, that's just plain not true. Also, with how convoluted the laws are right now, it could be pretty easy to be breaking a rule without even realizing it.
