Just from how it looks I think the girl said something really rude and disrespectful to an adult. Something =should= have been done, but not that. I think the girl is probably ill-mannered and has gone unchecked for sometime. It's a shame to have happened, but in situations such as that it's bound to.

Hell, it happened to me. Granted, it wasn't an adult who did it, but I shot my mouth off to the wrong person and got my hat handed to me. Wrong is wrong, but I learned something from my own actions: you can't go around speaking to everybody however you want and not even because you might get beaten up. The man is a monster for punching a child, but it could have been another 16 year old with a gun or someone with a bat or someone who wouldn't have stopped at a few punches. This easily could have happened a hundred different ways when you have someone who will speak to anyone in however a nasty manner at any given time. Again, I'll say for the record I'm not blaming her for getting punched, I'm blaming her for her own words. Reflecting on what I said to the person who later on beat me up, I feel embarrassed and not because I got beat up. It was a really shitty thing to say to another human being and =somehow= I needed to be checked. I wish it could have been done with words of someone wiser than me, but it didn't work out that way.
