Do we know how GM found these girls and persuaded them to participate? I just think that as a teenager I would have told her where to go. She must have thought they were suitable types of girls, so what was her criteria? Some teenage girls are very precocious while others are shy, but the girls required for this type of work must have come across as fairly confident. So were they completely innocent victims or older than their years and maybe already sexually active? The young lady in the PA photo certainly doesn't look unhappy, in fact she looks rather excited by it all.
