Experts: Sexual predators hidden in plain sight

The abuse allegations at Penn State seem unthinkable: revered assistant coach and prominent community activist Jerry Sandusky preying on eight children. But such abuses of trust occur repeatedly across the country.

Experts say respected people who set up charitable or social groups for children, only to be implicated in some form of child sexual abuse, are a frightening reality.

"I call them 'institutions of trust,'" said Portland, Oregon, attorney Kelly Clark, who has represented more than 300 sexual abuse victims. Some predators are so tacitly trusted "that when something like this happens, the instinctive reaction is, 'That can't happen here. We can't allow the mission to be compromised,'" he said.
