As to your question, I think it is reasonable for a woman to consider the area under her skirt to be private and not subject to being video-taped by strangers.
Perhaps the legislature could now address that issue. On the other hand, shall we have the legislatures try to criminalize every sort of obnoxious and unreasonable behavior under the sun? If so, what shall be the punishment for public farting of for honking at the car in front of you the second the light turns to green?
