How to stop hazing in my fraternity?

[Barbie's_Rush]

If they have been reported twice in such a short period of time and the results affected their pledge classes, wouldn't their national organization be well aware that there are hazing issues in this chapter? Why aren't they already stepping in to help change the culture? I find it hard to believe that in this anti-hazing climate that a school that has gone so far as to set up a hotline would not have involved the national organization at this point.
