Belmont Club on Jammers

The model that comes readily to mind is to regard Berger's escapade as a kind of information countermeasure. The most common ways to conceal information are to 1) create a decoy signal; 2) generate enough noise to blot out the underlying information; and 3) to reduce the signal of the original information which you want to conceal.
. . . As an exercise one can hypothetically regard the Plame-Wilson affair, the Richard Clarke book and Sandy Berger's bungled theft as representatives of these three kinds of information countermeasures. The first establishes a false "blip" -- the Bush Lied meme -- which misled intelligent bloggers like Oxblog's Patrick Belton for weeks as he followed this phantom echo. The Richard Clarke book can be considered a noise barrager type of countermeasure. It was for the most part a big sound and light show laced with ominous drumrolls with nothing behind it. When the time came to set Clarke's book against Condoleeza Rice's testimony at the 9/11 hearings there was curious lack of collision, as might be expected once you got past the boundary generated by a noise jammer. Berger's attempt to stuff codeword classified documents into his pants and socks looks like signature-reduction exercise on its face. It was an attempt to excise information; to create a stealth object which could pass through unnoticed.
. . .The significance of catching Sandy Berger in the act of purloining classified couments is that it enables investigators to "home-on-jam", to find the beneficiary of the coverup

He concludes by saying, "Remember that jamming needs to work just long enough for the real bandit to accomplish its mission".
