I've talked to a member of that chapter who told me that the pledges were provided with -- but not forced to drink -- alcohol by a clueless new member educator at their pledge retreat. Even so, it's indicative of a serious lack of foresight. I imagine that, at the very least, the girls who committed the "prank" plus the new member educator will be kicked out and the sorority will be on social probation for a semester or more.
