"Most of our difficulty stems from the fact that the individuals subjected to testing
must be unwitting... In the circumstances of potential
operational use of this technique, it is virtually certain that the target will be unwitting.
Any testing program which does not attempt to approximate this real situation will
result in a false sense of accomplishment and readiness...
It goes without saying that whatever testing arrangement we adopt must afford maximum safeguards for the protection of the Agency's role in this activity...
In considering possible alternatives to our present arrangement with the Bureau of Narcotics, we have considered contact with... police departments and prisons or prison hospitals. We have attempted several times in the past ten years to establish a testing program in an overseas setting, using indigenous subjects. In every case the necessity of making foreign nationals aware of our role in this very sensitive activity has made such options undesirable on security grounds...
While I share your uneasiness for any program which intrudes on an individual's private and legal prerogatives, I believe it is necessary that the Agency maintain a central role in this activity, keep current on enemy capabilities in the manipulation of human behavior, and maintain an offensive capability. I therefore recommend your approval for continuation of this testing program with the Bureau of Narcotics."
