In the case of Child Predators, these individuals are driven, experienced in gaining access and trust, target kids lacking strong supervision, and often have multiple victims before they are discovered. Guardians of children and teenagers need to trust their instincts to err on the side of caution and make sure NO ONE is performing any inappropriate conduct (touching, speech, nudity). Child Predator Jerry Sandusky took a benign event (have a teenager take a shower after an athletic event) and used that as an opportunity to abuse children.
