Clearly it exists. Several trannies have been arrested snapping under-stall pix. So much for privacy.
I understand the appeal of urban legends, and maybe it even did happen "several" times. It doesn't justify the government policing of bathrooms.
Call me a liberal, I'd rather you say libertarian. What kind of government do you favor that spends its precious time policing bathrooms?
Look, people need to act in all matters with common sense, common decency, and in accordance with the golden rule. If a pervert is lurking in the women's room, there's laws on the books dealing with that, laws concerned with assault. In a perfect world, there'd be no cross dressers who need to use the bathroom. But in this imperfect world, I'm not going to let politically-manufactured hysteria convince me there's a problem that needs the solution of more laws.
