SuBJECT: Counter-neasures Against Use of Interregaticn Aids and Techniques

.l. Our cirrent research project into the use of the Folygraph has already indicated its effectiveness as an aid to interitgation. It is time that we should consider certain counter-easures against modern interrogaticn aids vhich might be used against us by an unfriendily nation in either peace or war. Specifically, these additional aids are drugs, hypnotism, or the use of the two tcgether. Cur immediate objective is to acquire such basic and authoritative information necessary to brief our people on the manner in which these techniques might be used against then and as to what defensive measures can be taken to combat them. This knowledge is imperative to either individuals who may be exposed to such methods themselves or to staffs who are responsible for the operatiens and security of persons in exposed positions.

2. Accordingly, it is desired that you initiate a project.to study the current information and intelligence concerning these techniques and the possible defense against ttiem.

3. The entire prcblem has been discussed with the Assistant Directer, OSI who is in full accord vith the importance of such counter-measures. Arrangenents are being made for his further cooperation in the project.

L. I suggest that you asiters to take up this project.
