child abuse stories, types of child abuse

At this point in time, 20 states have laws restricting where sex offenders can work or live. For example, some states specify that registered sex offenders can't live within a certain distance of a school, day care facility or other location where children are to be found. I think anything that cuts down on child abuse statistics is a good thing, but I really wonder if these laws have the desired effect of cutting down on various types of child abuse. It's a good thing that sex offenders have to register with the local authorities and that anyone can look up the registered sex offenders and find out where they are living. However, I also know that most child abuse stories come from situations in which the child knows his or her abuser. Unfortunately, many child abusers are either family members, or family friends. Statistically, child abuse stories rarely involve total strangers, although it does happen, as in the unfortunate case of poor little Polly Klass, who was abducted, raped, and murdered by a predator who plucked her from her home.
