19 year olds should be aware of the dangers of having unprotected sex with strangers and the risks they take when doing so, 12 year olds not so much.
This girl was failed by everyone that came into contact with her that night. The shop that sold her vodka (so she looked 25 and didn't need ID then supposedly), the police that talked to her (so she came across as 18 on a night out in the city then), then this bloke who wanted to have sex with her so bought that she was 16, took her somewhere she didn't know and had unprotected sex with her, which turns out was rape because she was 12.
I don't see it curtailing women's sexual freedom if someone who says they are 16 to a random doesn't immediately get sex, I see this as giving women sexual freedom. Freedom to experiment with sexuality without it becoming full on unprotected sex within a short time of meeting someone.
She was 12.
