This disabled chick (more mental, she's not physically handicapped) is really scary. She attacks my friend constantly, and just today, she grabbed her by the leg and dragged her into the middle of the hallway while punching her!! She also goes around the hallways and hits other people! We've talked to school authorities and they refuse to do anything. The only other option we really have is to punch her out or even kick her ---. Any advice? I know this sounds REALLY weird but this chick is freaky.
