Deputy Chief, I & 8 Staff 27 October 1950 T)iore are a few nnswera to certain questions which viore brought up at, the conference whicho because of the timo limi-botioneg I was unable to discuss at the time,, I am more 2 convinced tlinn ever concerning the necessiiy of the preventing or the dianom:lmation of knowledge that re are using a hypnotic toohniqiiso, Be- cause of this, it mooris inridviaable to rely upon the-oral technique of drug administration*, Although this method mF.7 2well succeed in a large portion of Cases,, 'in those in rhioh it fails# the subjects would have reason to Icio%T that hypnotic attempts had been tried and miglit well priss dn such information to other people. In our recent research project, no word or mpnipulation which could be construod by tl2io individuals affected ex the commonly recognized hypnotic toohnique. Tlio sam general objeotionn would bo applicable -to the surreptitious use drugs:by the agents in that the nttomplv to use anything aimi of lar to a liypnotic 2 technique might be recognized by tlio subject, As you knows since time imnemorial,, &t-tompts have boon made to ext-relei, information from Individuals under the influence of L,.Icohol,, sometimes with success,, often with failure. As a matter 2 ofacto other drugs used to affect tlio stskte of consciousness axe not much tiiffereii-L- in their effects than tllrtt of nloohol* It in probable tliai-, the Lntrnvonous uot3 of solu- tions of alcohol might be just as e.Cficacious as tha2t- of any uf tlio preparations we are now ucinc* In P, coi.-il)arison between -"-,he effects of alooliol and the otlier drugs. it must be remembered that L-here is a wide dif.Corenoo in individual response of'them4 'ite shall continuall)2r strive td attain more L-nowledga and better tooluliquoso,, In the moantimes my genoroll feeling is that because we have accompl:Loliod tliinge which seem almost impossible,, the authorities concorliod almost believe i-I t nothing 2 in iinpot3iiiblo* As you knowo 'there are definite 1Jmita-uioi-lsl, espeo-lally aiilco we are so greatly handicapped by popular and official prejudice a@,,slnst come of our methods* Concernirw, the discussion of tl-io -@,iork at- tli() 2 an to tlio dovelopmont of a better Polyr-raph, it is my opinion a iG operaj%-Iors ;Yill always -than the machino,# I really believe t@iat successful D.
