I'm just catching up with the older podcasts and while listening to you guys "feeling like criminals" because of the bad reputation we get lately, I wondered why you don't talk with those people?
If the cops sit in their car to watch, say hi and do a little small talk about how they experience the situation with the new regulations or if they experienced something bad with the hobby. Introduce yourself, offer advice if they ever have questions regarding the hobby or suggest a little demonstration on the technology today.
If you think neighbours might feel what you are doing is illegal, talk to them. Show them what you do and how.
If you feel people are afraid of doing 3D maneuvers being "out of control", ask them to watch and explain every movement before you do it so they realize it's not something random.
It's our job to make people feel safe regarding the hobby. You can always explain that the bad sightings in the press are just the ones they hear about, that most people are indeed following the rules and not everyone is a bad guy, just because he has a remote controlled aircraft.
