1) Yes there are safeguards, and this is a clear case where the safeguards had failed. Sure, Ben M. may still become a qualified physician, but the point here is that there are other more worthy applicants. Ben M. did not earn his spot.
2) I have many offers, and I'm not approaching this from the "OMG this is why I can't get into med school" perspective. I'm coming from the "This should never be allowed to happen if the medical school admissions wish to maintain its legitimacy" perspective.
3) If you have multiple offers, why would you CHOOSE to goto a school that has a dean that lacks integrity? It is not foolish. If I was interested in UF, I would take my 200k somewhere else, to another school where I trust the quality of my classmates. A mass exodus away from UF would send a clear message: **** like this should not be tolerated. I trust that this would set a precedence and ultimately benefit the medical school admissions process. I'm shocked that you do not see the benefit of that. Medicine as a profession relies on the public's trust towards the doctors. If there are even a few cases where people are able to bribe their way into medical school, it would seriously affect the public's perception of their doctor's competency.
The end goal here is not a mass walkout, but a mass walkout of their most qualified students. In the end, the total number of admitted students would not change, but it would likely funnel some of the lesser qualified students to UF, lowering their GPA and MCAT averages for the incoming class, which inevitably ruins UF's reputation. This, in turn, would likely force UF to replace Dean Kone.
