Um, I'm not sure what you mean because tyra thing isn't on in my time zone, but maybe they shouldn't fight in public? Isn't it illegal to get into a serious fight regardless of the circumstances?
I think the whole idea is just wrong and stupid. People who watch the fights have no right of recording it on their cell phones or whatever and putting it on youtube. They just want to get attention and feel better about themselves for something they did that was none of their business. Then after they post the video, the people that were in the fight are mad at them and the people who posts the videos are likely to get into trouble.
