such a terrible and devastating loss of precious life!  by all accounts and reason, no one - individual or organization or institution or law - may have been able to humanly avoid or avert this catastrophic event.  hence, to preposterously attack any one of these or presume that any one of them would be a logical basis for causing this event, either directly or indirectly, is insane and without merit!  heart-felt and most sincere condolences to the town and the families living there.
