I don't know Frank Jackson from Adam and couldn't even pick him out of a picture unless the caption pointed out who he is. But people tend to have excessively superhuman assumptions about public officials or private executives--anyone who has departments working for them. In the short term, the fact that you have 5 or 50 or 500 or 500,000 people "working for you" means precisely jack about what you're likely to know when put on the spot about a breaking news development, or even about what your own department(s) is doing at any exact moment in time five or ten levels down the chain.
I've got people working for me. At this very moment, there are probably between 100 and 200 matters moving across their desks. I have basic familiarity with maybe forty of those, working knowledge of maybe ten, and detailed knowledge of at most five. Some of those that I have general working knowledge about might be ones that I had detailed knowledge about last month, but I've long since forgotten in the rush of other matters that have risen to the top of the priority list, and no one can hold everything in brain-RAM forever.
