Also, I think that statistically you are more likely to raped by someone you know - either a friend or close family member. No-one ever makes a poster about that.
Actually I can see why. The lack of control makes people uncomfortable and they want to be able to pick out the thing that victims did 'wrong', to ensure that they can avoid it happening to themselves. Psychologically understandable, but a bit bloody harsh on the victim. The truth is, it's not something you can control (like a lot of life).
