 And right after President Kennedy was assassinated, there was a time when they were leading him from the jail to the courthouse. And they went to an underground garage. And a couple of reporters were waiting for him. And so they started asking a bunch of questions. And he, of course, denied everything. But they were playing this recording through their voice stress analysis. And they would overlay their voices and said, he's lying here. He's lying here. He's lying here. And I was thinking, boy, that sure would change history and everything if you could have that kind of technology in the 60s.
