Unfortunately, I'll need to dig some to locate the horribly terrible pics. before I can speak honestly.
In the meantime go read the original accuser's autobiographical section. Emotional investment and fragility and identity confusion probably play a small part in the judgement of someone with a long 15 years' worth of wedding photography under his belt.
Like some others, the idea of drugs or prostitution applied to kids does not excite me. It does the opposite. However, one of the most beautiful memorable photos I've ever seen was by Sally Mann of her daughter sensually pretending to smoke a cigarette, with another young girl in the blurry background trying to stand on stilts. She caught a lot of flack back then. Do these photos convey something deeper as well?
