I can concede that in some cases, based on the age of the child, and how the spanking is administered, that it might not be classified as abuse...but I was under the impression that this was a very young kid, maybe 4 years old? I have a 5 year old, and there's no way he'd be able to comprehend physical discipline, or be able to learn from it.
The worst part for me is that I've heard my kids yells when they've been hurt, and I've heard what it sounds like when they are legitimately afraid like when they have nightmares. I can just imagine the sound his child made the first time he got hit with the switch. For AP to hear that sound, and then be able to continue to hit him some more turns my stomach.
He should at least get what Ray Rice got, if not more.
