I understood that it was his son, and I didn’t mean to infer disbelief on that point.
It could be revealed that his son did plan on attacking. It was my thought that the family could have thought the issues from earlier in the day were resolved at least to the point of being civil to each other.
I’m not trying to make a point here other than several scenarios are possible.
I see what you mean now. I’m cross eyed and thought you might have missed the comment about the son. Maybe there will be details soon. You’re sure correct about several possible scenarios, here.
