Cheese - this is very timely. Thanks for posting this. This is the third awful story of child abuse I've heard in a week. I was late to work this morning because I read David Pelzer's book, "A Child Called 'It'". Several hours later, I am still in a depressed funk from what I read, and relating it to what I experienced myself.
Regarding 'witnesses' - this is a tough one. While we like to get on our internet tough-guy horses and ride in to save children from abuse everywhere - it is much more difficult in real life. Child abuse goes unrecognized EVERYWHERE, ALL THE TIME. And how does one get involved? How does one prove that child abuse IS ACTUALLY OCCURING? How does one intervene legally, and in a way to guarantee future actions stop? The parents lie about it, or teach the child to feel ashamed of it, or simply enough - NO ABUSE OCCURS WHEN OTHERS ARE WATCHING.
Honestly - this is where I wish for reinstatement of the "Eye for an eye, tooth for a tooth" method of justice. If convicted, make the grandmother and step-mother run a proportional amount of time (if 3 hours to a child, X hours to an adult). I want to see them gasping for breath after 50 yards, knowing they have HOURS in front of them. Oh, what's that? They aren't in a physical condition to run for that long? The problem will take care of itself. Instead, if convicted, they will get to spend years in prison, on the taxpayer's dime.
