Not sure what your astonishment is, but piazza absolutely knew that he was participating in a drinking event. I believe that he sent a text message prior to the event acknowledging that his expectation that he would engage in heavy drinking. That said, the GJ Presentment does not even describe what I would consider to be a particularly heavy or unmanageable alcohol consumption as a part of the activity, which I consider to be light hazing at most.I have continually spoken out in this thread, and others, about rushing to judgment, but some of the posts here which attempt to explain away excessive alcohol consumption (e.g. "it was voluntary") and hazing astound me. I have limited time today so I will leave it at that.
The real problem here is what happened after he fell, not what led up to it. The failure to get help seems to me to be a result of some combination of the internalized nature of the injuries, the inexperience/ineptitude of the other kids, and their fear of consequences of their underage drinking event at a dry house.
