I wasn't particularly claiming it was used by a large portion of those in intelligence; my claim was that it was an overwhelmingly large portion of the uses of the term, and those familiar with it at all (and not just guessing the meaning based on the fact that it's made up of two familiar words) are most likely to have heard about it in Burn Notice (which apparently had ~5 million viewers) or read it in a Tom Clancy novel (of which there may be 100 million copies in print), if they didn't read it in a recent Al Jazeera or Washington Post headline.
