Sometimes... getting caught while shooting a Nude In Public can be a GOOD thing, such as when photographing someone else in a city park and getting caught by someone like Lola, who asks if she can "play too"...
I bet the complainer doesn't say a thing as she watches immodesty on the TV or on a movie. In the USA, I think a police officer has to actually catch you in the act. If witnessed by a civilian, just deny everything. Your word against theirs. Always have an exit plan. I would do activities not too close to home. Thanks Lola!
