Parental Intervention

Your younger brother is a terror. He bites, kicks, steals your CDs, capriciously deletes your downloaded music and ravages your room whenever you step out. You have had it. The easiest thing would be to have your parents intervene somehow (putting a monitoring system on the border of his room, preventing violations to your sovereignty) but they are busy. You pick a week, a week where you can be grounded with impunity, and beat the crap out of Johnny. You don't kill him, but you wail on the brat, and wail good. Your parents are incensed. You are the older and more mature child, how could you do something like this? They ground you for a week, maybe the whole month, and reluctantly send your brother to therapy, recognizing that the satus quo is unacceptable. And you have successfully brought an end to the terror.

Unfortunately the UN/EU are not as reliable as my parents, but it is better than the status quo.
