Sexual Perpetrators:

A Sex Crime of Control, Power and Violence
A perpetrator gravitates to persons who are too polite to fend him off...
A perpetrator gravitates to persons who are shy and anxious who are unable to tell him to leave...
A perpetrator gravitates to a person too dependent to be aggressive...
A perpetrator gravitates to someone too impressed by status and power to be able to do the right thing. 

                The perpetrator associates with adults who can't address this issue and charms people who do  not believe this could ever happen.
