Actually, this article doesn't go into all the details about the charges and the case. Legally, its not pornography under Florida law. The big deal was that a few girls were underage. However, they produced fake ID's and presented themselves as "of age". Now, unless a girl testifies in court she was explicitly told to lie about her age, then they have no case, legally. PERSONALLY, I think you could argue that GGW didn't take the best precautions to ensure the girls were of age, but apparently the court didn't see it that way. Personally, again, I doubt the producer cared if they were 16 or 22, but I can't prove that.
In addition, there are more charges concerning public nudity and enciting public nudity. The penalies aren't very stiff, though.
Pun intended?
