I guess we just disagree on what the laws state. I think giving a specific list of what kinds of injuries are not tolerated is pretty straight forward. I'll just wait and see what, if any, criminal charges AP receives.
The only thing that will tell you is whether "child abuse" is illegal, which everyone agrees on.
Had Peterson hit his son with a tree branch,
but done so in a manner that did not leave any marks, he would then just be a loving parent who believes in stern (but reasonable and totally legal) discipline. As cited in the paragraph above, a man
in Minnesota was acquitted of child abuse in 2008 for striking his 12-year-old son 36 times with a wooden paddle.
