Re: If it is illegal to 'upskirt'
Can't have it both ways.
What arrant nonsense.
If a woman wears a bikini in public, it's normally in a place where she expects to be looked at - for example, on a beach or at a swimming pool. And she can't really complain if photos are taken of her. (But even if a woman is wearing a bikini in public, I think it's reasonable to be hacked off if someone is taking a photo of her as if it were an upskirt - no matter how legal it is.)
A woman who is wearing a skirt is reasonably entitled to not expect a man to be trying to look up said skirt - and is certainly entitled to assume that he won't reach down with a mobile phone to take a photo up her skirt.
And even if a man gets a glimpse up a skirt, it's just one of those things - quite a kick if you're a teenager, as I remember. But taking a photo of said view is just damn pervy. It's the difference between glancing at a woman's cleavage and staring deliberately at her breasts.
