Not doubting for a moment he received head injury and broken nose, but can someone suggest a reason why he would not go to a hospital for that? I’d be worried about possible hematoma, or passing out and winding up even more injured on the way home.
He probably needed a drink. I would after this order of events..
He went to his own doc the next day. That’s good enough for me. The man was most likely in pain, exhausted, in shock (after all he just had to pull his gun and fire to protect himself), and not thinking 100% about his ‘health’ problems. I too in that case would just want to get home to the wife and kids
His physical injuries were probably not his main concern. He was quite shaken up.
