Could this be an abusive situation?

yea my arm still hurts and it's been a good 15-20 minutes since. My parents don't do anything about it. They just tell ME to get over it, and I should just walk away from the whole situation. It wouldn't be so bad if my dad hadn't been abusive so my educated guess is that my brother learned it from my dad.

My brother thinks he's the sh*t and is above and beyond what people tell him to do and can't do. His excuse for jerking me out of the chair was that he hadn't been on the Internet and that I had probably been on the Internet all day, which I hadn't. This is my first time all day of being online. I got on to check my email and greekchat. Right now, he's not allowed on the Internet for the rest of the night, I think. If it were up to me, I'd jerk his license away and kick his butt from here to Altoona. Unfortunately, I am only his older and only sister/sibling and can't do anything because I am not the parent.

I realize he shouldn't resort to physical violence for anything no matter how large or small the situation is. What should I do? The police where I live won't do anything because they are small town cops that don't know how to do their jobs and are afraid of reporting anything due to the fact they don't want anyone they know or are related to to be front page news on the local rag they call a newspaper.
