in the USA nudist type pics are legal but 'sexualised' pics aren't...but then what is 'sexual' to one person isn't to another.
These laws are getting rather complicated and you will probably end up at the mercy of a magistrate or judge and what their definition is. A bloke got arrested here in Sydney just the other day taking snaps of someone's naked kid at the beach..but why isn't the nudity itself a crime or what about those just looking and memorising the image in their brains ?.
The charges may end being very different of course...obviously he was a nuisance but it will be interesting to see how this plays out especially as 2 cases of men arrested taking photos of topless ladies at Bondi had their cases turfed out by magistrates ...because they were charged with the wrong offence.
BR is correct to some degree..some may find even these 'scanner' images sexual..not just of children but aldults as well...ther could be a whole new genre on the net.
we're all going to hell in a handbasket anyway and I reckon the next terrorist step is swallowing some sort of explosive !! what then ?
