This is absurd.   Erin should be applauded for possibly saving a life, doing the right thing.  Have we reached a point in this country where we call  "Good evil and evil good?"    I hope that school system is bombarded with letters in support of Erin. Punishing her will only cause other students to refrain from calling a friend when they are too drunk to drive, and while ideally students should not drink at all, it could save a life.
