Most sex offenders choose to play nice people, knowing that people believe the surface no matter the evidence to the contrary.I realized when I was a teenager that people believe words more than actions - play nice, friendly and sociable and they will like you more than if you're introverted and do nice things for them.Being perceived as nice is the sex offenders number 1 protection. People want to believe that evil doesn't exist or that it's rare and easy to detect.Example: The author was invited by a friend to take their daughters to a dance place for children. The place is full of kids jumping around to loud music and ignoring their parents on the sidelines.Dr. Salter notices that the father of one girl keeps enthusiastically dancing with his daughter and the daughters of Salter and her friend. No one else's parent is dancing, and this man is paying lots of attention to the girls.She walks up and taps her daughter to take her away, and he actually grabs the child's arm and pulls her to him. Salter has to yell over the music that she's the mom.Salter talks to the teacher at school and learns that this man was the only parent on a field trip and paid so much attention to someone else's daughter that the teacher thought it was his child.Salter advises the teacher to keep him away from her daughter, then warns her friend: Within a week or so the man's wife or daughter will call and invite their daughters over to their home. Turn down the invitation.Sure enough, there are soon calls and invitations. In spite of Salter's expertise with child molesters, her friend gives in after a few invitations and allows her daughter to go to this man's home to play with his daughter during the day.Why? He's so nice. He wears a suit, he works, he has the social graces of politeness and friendliness.Rationalization: Plus, he'll be at work, as if he couldn't come home early.The vast majority of children will not report abuse or even rape.Ditto with rapists of adults.A rapists spends 6 months working small repair jobs at a house where a woman is home with her children while her husband works. He's planning to rape her from the start.He knows the neighbors see him and his vehicle around once or twice a week. See him fixing things, entering the house.One day he rapes her. He avoids conviction by claiming that they were having an affair and she's lying. Most people believe him. He set the whole thing up knowing how easy it is to manipulate what people think.And he had a prior conviction.
