"Need I remind you of the governing rules of this school regarding fair and unfair punishments Albus?" she replied nonplussed. "Mr. Potter has just been attacked by another student who has not been punished while now two members of the staff that failed to protect him have tried to punish him; first for defending himself then for voicing concerns about his safety. He spoke honestly without malice. He didn't yell, threaten or use foul language. If that's not enough Albus, I'll finish by pointing out that there is no rule that says a student can be punished for hurting the headmaster's pride."
