I do think there is some complication concerning that. Walking in on something like that would be incredibly traumatic (obviously not to the level that the child is experiencing), it could be compared to walking in on someone's head getting shot off or something that so people would react differently depending on the situation. I can kind of see why he didn't physically intervene. That said, I would hope that at least you process what is going on and what you just saw, you would tell someone other than your father or your boss (aka the police) Yeah, I can see your point. Sometimes people stop functioning correctly when they see something that traumatic.
