i think your daugther did what was right... it doesn't say she jumped into a fight and started throwing punches, it says she tried to step in between the two who were into it and seperate them....

guilty.. guilty of what exactly dude? trying to stop a fight? i'd rather be known guilty of trying ot stop a fight, then getting in the middle of it and throwing hands...

and actually that she saw the level headed way out of it and tried to prevent the violence is something to be proud of... not something that needs punishment, or any further action....
