The guy did the right thing. Notice how all the sports announcers are making it sound like a joke. People would be up in arms if he did that to her. Women think it's open season on guys.
If you're a big guy, you can't even TOUCH a young lady. My ex-wife came at me with a knife, and I held her wrist and took the knife. The next day she was showing her co-workers the bruises where I "abused" her. One of them asked me about it. I showed her that the fingerprints could only be from a defensive posture, and that was the end of that.
I didn't report the incident, because I didn't want to be involved in a DV arrest and lose my Firearms Authorization Card, even if I was exonerated. In Chicago, since she was bruised, [b]I[/b] would have been the one going to jail, since there would have been no evidence of injury to myself. I would have had to let her stab me, THEN take the knife.
I left, and haven't looked back.
