This discussion will focus primarily on the behavioral aspects of the sexual exploitation of children perpetrated by adult offenders who have an acquaintance relationship (i.e., not strangers or family members) with their child victims. Some of the information, however, could have application to acquaintance juvenile offenders and other types of child-molestation cases. Although some legal and technical aspects involved in these cases will be discussed, those are not my areas of expertise. The law and emerging technology can change rapidly and significantly in a short time. Experts in those areas should be consulted before applying this information, but underlying human behavior tends to remain the same.
