Mr. RUBY. All I want to do is to tell the truth, and the only way you can know it is by the polygraph, as that is the only way you can know it.

Chief Justice WARREN. That we will do for you. 8

Following Ruby's insistence on a polygraph test, the Commission initiated arrangements to have the FBI conduct such an examination.9 A detailed set. of questions was prepared for the polygraph examination, which was set for July 16, 1964.10 A few days before the scheduled test, the Commission was informed that Ruby's sister, Eva Grant, and his counsel, Joe H. Tonahill, opposed the polygraph on the ground that psychiatric examinations showed that his mental state was such that the test would be meaningless.11

Chief Defense Counsel Fowler had objected to the test. He conferred with Jack Ruby in his cell and then returned stating that
