Would anyone here wish that people were not very careful about child pornography?
Is it easy to view a photo and say "that is just a cute photo taken by a loving parent" or "that photo was taken to stir up the lust of a pedophile" ?
Well in some cases it would be easy to tell, in other cases it could be very difficult.
The photographer's decent intent is no guard against a pedophile's obscene excitement.
It is a difficult issue. I, for one, would choose to have people very aware of the possibility of a child's danger even at the inconvenience to a photographer.
