It is estimated that in 80 percent of the cases of sexual abuse, the perpetrator isan adult known to the child. Only 20 percent of the incidents involve the menacing stranger children are warned about. Many other myths accompany the "stranger in a raincoat" perception of child sexual abuse. Sexual abuse usually does not occur as an isolated incident, but is a long-term situation which develops gradually. Sexual abuse is not always accompanied by violence and physical force; it may be the result of subtle forms of coercion, such as the use of adult-child authority or parent-child bonds. Young children do not have the developmental or emotional capability to choose to engage in sexual activity with an adult. Therefore, all sexual abuse, regardless of the form of coercion employed by the perpetrator, is the result of force.
