Mr. Herndon. Now, let me inject this, Mr. Ruby. If these questions when I ask them, if you have something in doubt in your mind of how to answer it “Yes” or “No,” just refrain from answering it, and we’ll go back after the test and discuss it.
Mr. Ruby. Very well.
Mr. Herndon. In other words, I want you to be able to freely and truthfully say “Yes” or “No” to these questions. If one of them leaves any area of doubt in your mind and you are hesitant to answer it, feel free not to say anything, and we will just proceed, and after I stop the instrument, I will then go over that question with you. All right, sir?
Mr. Ruby. Yes.
Mr. Herndon. All right, Mr. Ruby, I’ll just briefly hook up the instrument and I’ll probably run it for a little while just to get it adjusted to you, and inasmuch as you’ve never had a polygraph before, I will explain the instrument’s parts to you. You can see here, Mr. Ruby, I have a rubber tube and I’m going to place that around your chest, sir. This is what we call the pneumograph and that will accurately record you respiratory pattern as you inhale and exhale. Would you be kind enough to raise your arms, sir?
Mr. Ruby (complied with request of Mr. Herndon).
(Reporter’s note: 2:58 p.m.)
Mr. Herndon. Now, as you can see, as you inhale the tube stretches, and as you exhale it decreases in size and I will have a tracing of it on the polygraph.
Mr. Ruby. Yes.
Mr. Herndon. During the examination and as we run the test, I would appreciate it if you would sit perfectly relaxed, rather straight in the chair, with both of your feet flat on the floor. Now, that will record, during the interview, the tracing of your breathing, and I want you for this reason to breathe perfectly normal and perfectly relaxed. Now, the next thing I want to put on will be on your hand and I’ll put it on your right hand here. I notice you have one finger cut off on that hand. What happened there, Mr. Ruby?
