I vaguely remember a legal case from 20-30 years ago in which a young girl sued and won judgement from a municipal swimming pool when she became pregnant. An intact virgin, she was being harrassed by a group of boys who ejaculated in the pool. (Nice kids). The pool was sued for not protecting the girl from the boys and because the pool was not sufficiently chlorinated.

I make no arguments for this, just reporting what I read many many years ago. (For those claiming this to be some kind of urban legend, I do remember reading it.)
