Do you know how to spot a molester? Dr. Ablow says one way is direct evidence—pornographic material involving children. And when pornography is coupled with drug use, it's a clear sign that a person is detached from reality and has trouble caring for other people, he says.
Another sign is an estrangement with children from a previous relationship. Don't assume that the kids have a problem. "Become an investigator," Dr. Ablow says, "Be more paranoid, not less paranoid."
