When I was a stock analyst, I gave a couple of talks to a B-school class on stock analysis. You could say I was there as a representative of the stock analyst profession, but I was NOT doing stock analysis during the class.
Similarly, King was not doing journalism during McCann's class.
Really? Then what was he doing there? McCann didn't bring him in to tell his class what swell guys his colleagues are?
You still haven't answered why McCann brought him in, rather you dodged it exactly the way King dodged the question about Mortenson.
