I watched the video; if nothing else I hope he caused the perp a moment of terror that someone was about to get even, with his words and then by charging him. He’ll have that to think about when he’s in prison a million years.
He knew the court would not allow it. And if it had, he’d have a lawsuit.
Sorry, these things must be referred to God. God can be maddeningly (to men) even handed. Why didn’t the father teach his daughters that some things are more important than even Olympics? Too little, too late, wrong way.
