Denny it completely and tell them that he’s been threatening her and that this behavior is further harassment. There’s a decent chance that a piece of shit like this has other incidents in his record and if you haven’t made a habit of threatening old men then they’re not going to do shit.
My concern is escalating it directly with him like that is tempting him to escalate directly with her. He knows that you’re not the kind of person who regularly threatens people because you didn’t do it the first time it happened.
That’s where the centuries come in
