While some child predators are caught in the act or confess to their crimes, in many cases the signs of child sexual abuse are so vague that the people who observe them wait far too long to investigate or fail to act at all. They may feel that there’s no proof of the abuse, or that acting on suspicion will get them nowhere. Still, there are some behaviors that are far more common among children who have been sexually abused than those who have not. Anyone who becomes aware of these behaviors should be aware of the likelihood of past or ongoing sexual abuse and act accordingly.
