The lines between all of these are fuzzy. For some discipline and fear are basically the same thing. As long as you are more afraid of the authority figure than you are enticed by the transgression that would bring punishment, you most likely stay in line. And you are totally right, we don't know how any of these events actually went down. We just know what we hear in the news/internet.
I have always felt that AP got more of a pass in the court of public opinion because he was an already established "star" and people had already decided to like him. In contrast, Hill was tarnished before anyone had really heard of him in the NFL...so it was far easier to just write him off. I am not advocating rooting for Hill or not rooting for AP...just these kinds of things have always intrigued me in the extreme and passionate fan reaction to them. Another example is that Ray Lewis is in the HOF and Rae Carruth went to jail. Both are almost certainly heavily responsible for another person being murdered. Anyways...
So Greg Lloyd likes to pull guns on his wife and son:
