Have you seen the video? He wasn’t supposed to hit her. But when you repeatedly are attacked, extending your fist, which is what happened, is probably going to happen eventually. I’ll agree that he doesn’t know his own strength, but the video doesn’t show him putting anything behind it. He stepped back and she kept attacking him, he extended his fist and she falls like a sack of potatoes. It isn’t all out of proportion. He gave her about the lightest hit a guy like him could have given. Look at the video. I’m not at all happy that I have to call this one like I see it, but he isn’t in the wrong here. This isn’t an “I’m afraid for my life” swing, but a tiny “stop chasing and hitting me” defensive punch. Look at the video.
