I heard an English radio programme where all kinds of soft-voiced spooks were phoning in (!) to talk about the bugging.

One of them talked about the negotiations for, I think, Suez, when bugging the opposite side meant that "we had sight of their cards before we went intot the talks".

I thought it was *psychologically* very interesting that an intelligence operative would use a metaphor based on cheating at cards when he was talking about this subject. They know what they do is wrong.
