It has been reported that there are two rival groups at the high school, and a fight took place between two girls, one of which was KG, the day before the brawl that left her critically injured. It has been suggested that the brawl was perhaps a continuation of that fight, and it has been reported that the accused teen was a friend of the girl that KG was fighting with the previous day. Given that likely scenario, I just do not believe it is realistic to expect any teen in her place to just take a punch, walk away and report it. I'm not sure that she would have been allowed to just walk away, as there were several other teens there, apparently from the rival groups, and even if she had, I think that would probably only further escalate the friction between the two groups. When one is perceived to be weak or a squealer, they get a target on their back. MD probably felt that she had to fight, but sadly, she took it way too far, and now, two young lives will probably never be the same again. JMO
