I'm no lawyer, but he seems to clearly make first aggressive contact. More importantly, I think the question of her being a woman is covered under your responsibility to use appropriate proportional force if you feel you are "defending yourself." It's going to be hard to convince anyone that his response was proportional to the "threat" her pussy punch posed to him, even if you buy his lawyer's argument that she initiated the incident, which looks dubious at best. In fact, judging from her response, it looks like she may have felt there was some harassing contact as they jostle for space. Assplay in other words. Or grabass if you prefer.

More disturbing is the bartender's outfit.

It's too bad the whole bar didn't just blow up and kill everyone inside.
