If you had a sick enough mind to want to manipulate a child into having sex acts with you, without complaining to anyone afterwards, what would you have to do?
You'd have to do exactly what the FLDS and Jerry Sandusky do. You would have to gain some sort of power and influence over the child's life.
A less sophisticated child rapist might simply kill them afterwards, or tell them if they tell, he will come back to kill their mommy and daddy.
But Sandusky and Jeffs were the sophisticated, civilized variety of child rapists, so they manipulated rewards.
Take a look at this 1998 FLDS run Alta Academy school reader. If this isn't grooming children to be abused, I don't know what you could consider it. They couldn't even locate a model that didn't have visible injuries to his face? They used it in the lesson! They taught these children that their hurts and pains were to be suffered silently. Does anyone else see how self serving this grooming is for pedophiles and child abusers? Anyone?
By the way, the "daddy" in this "teaching material," is now sitting in a Texas prison.
