@panpacific, I agree with preventive measures. I even included preventing ruining life of the potential aggressor as one of the reasons to my dd that she should be aware of her safety and psychology of people around her, as crimes are often opportunistic. I believe that her studying developmental psychology helped her to understand what boys go through, and understand who they are, no less and no more.
On the other hand, many 13~15 years old girls do not have benefit of studying developmental psychology in depth nor vast life experience, and have only vague, superficial understanding even with all the related education. Science also shows that they can simply be petrified with incoming danger. That’s why laws are made to protect them.
Therefore when it comes to between a girl giving the mixed messages (or just freezing out) and a boy acting on his perception, I see it clearly as the aggressor’s responsibility. And I hope that you didn’t mean covering up the incident like it never happened by giving a second chance.
