This document includes personal observations in the form of the 10 Commandments of Counterintelligence. "I have chosen the form of commandments because I believe the basic rules of CI are immutable and should be scrupulously followed. In my view, it makes little difference whether the adversary is the Russians, the Cubans, the East Germans, the Chinese, or someone else. It likewise makes little difference whether we are talking about good CI practices in 1985 or in 2005. Unfortunately, as I watch US CI today, I am increasingly concerned that the principles I consider fundamental to effective CI are not being followed as carefully and consistently as they should be. These commandments were not handed down to me from a mountaintop, and I make no claim that they are inspired or even definitive. They are simply the culmination, for what they are worth, of my experience. They are intended primarily for my fellow practitioners in CI today, but also for any younger officers in the Intelligence Community (IC) who might someday want to join us."
