Office of NYC. I called this. He knows he's an asshole and doesn't want to be exposed any further. As has been reported, he went to the Park with dog treats in his pocket, when he doesn't have a dog, in order to lure off-leash dogs to him, which is what he did with her dog. If you have a dog and a stranger complains about your off-leash dog and then tries to lure it in with treats, well, them's fighting words. That makes you a certifiable asshole.
She lost her job, has been arrested, has been brought up on separate NYC Human Rights charges, and has basically been canceled over an incident that his behavior sparked. What a tragedy. If they BOTH had acted like adults none of it would have ever have happened.
