So I'm not the only one who thinks he'd probably be violent to her as well.
as she/he is still looking for the jacket, you could mention that it is probably still at the place they were kicked out of, and they can pick it up when they apologise and sort out the damage.
If it does come up, and you actually talk to her about it, you could point out that there's a reason that so many people in her old town had an issue with the guy and why people in your town are having issues with the jerk - it comes down to one common point - the guy is an a**!

I generally* allow idiots one swing at me, as I generally am quite a bit bigger/stronger and should easily take them, telling them that's their free shot and next time I'll be hitting them back, hard! Almost always works and no further action is needed and, if it is, well, they were warned.


*Sometimes you don't have that option, and you've just got to deal with as well as you can (fight or flight) - like bigger guys just looking for a fight because one is seen as being a quiet person and an easy target. Fortunately it's very rare.
