The Honorable C. W. Bill Young
House of Representatives
Washington, D. C. 20515
21 June 1985
Dear Mr. Young:
Followin u on our telephone conversation yesterday, I am sending
you a copy of estimony before the House Armed Services
Committee las a ope you'll find it useful.
I personally have no doubts that the polygraph is the most effective
tool we have to identify and screen out individuals whose employment or
affiliation could jeopardize our national security.
As you can see from Bill's remarks, in 1982 polygraph interviews by
CIA developed significant information not surfaced by other techniques in
70 percent of our applicant cases, 25 percent of our probationary
employee cases, 31 percent of our periodic reinvestigation cases, and 43
percent of our industrial cases. .
I certainly remain a staunch advocate of administering polygraphs to
anyone having access to sensitive intelligence data or national security
information.
Sincerely,
04 I'li.
John N. McMahon
Deputy Director of Central Intelligence
