First of all, many thanks to all of you who tried to answer my procedural question regarding the flow of information on acceptance/rescission status between schools. That was all I really needed "advice" on and I didn't think it "strange" to ask that of a group of people, regardless of age, who collectively have an enormous amount of knowledge of the med school admissions process. Thanks again.
Second, I understand many of you are curious regarding what specifc comments were made by the student in question. I was not there and School A did not provide that information. I do know that no faculty or staff were involved and the origin of the complaint was some fellow second look attendees at some later date. The student was not asked for his version of events by the School at any time. In his version of events he was very very drunk and made some comments that might easily have been offensive to individuals from one area of the country (these were not racial or gender based, but they were definetely perceivable as offensive nonetheless). Other attendees have supposedly said that nothing offensive was ever said, but those witnesses might be biased.
I'll let you know how this all turns out in a few weeks. There are lessons to be learned here for all of us.
