threatened in TSA line at PHL

I know TSA can’t do anything, but really bummed with how Philly police and TSA handled a grown man telling me he was “going to smack the shit out of me” if I pushed his bag again when I asked him to move his down previously. And he said it in front of his daughter- who wouldn’t even look at me when I asked him to repeat himself. Not sure what could have been done, but I think “man threatening woman by herself in airport” should be something that is not swept under the rug.
