I worked at a film developing place while I was in high school. We would develope nudity, but touching was illegal, any kind of touching. You could be naked standing a foot away from another person, and if you were holding hands, we couldn't release the picture. Also, any type of illegal activity is supposed to be reported to the police. There was some guy in my area who posed with his "pot collection". The police were called and waiting when he came to get his pictures.
We're talking usa the land of freedom here right? wtf? i thought only child porn and totally illegal $hit was not ok. Other stuff could be considered art or something.
