I wonder if knowledge is like paint. It can be spread around, but you can always miss a spot, and have that one person who managed to miss the one bit of data that everyone else knows. Given all the information that it is assumed that "everyone knows" one can imagine that everyone might have little gaps like this. How would you know?
