Admitting the leak? I thought she lied during her poly?
I have go to Howlin's thread and back to the unexcerpted sections of this one before I can answer any questions.
They wired her up, questioned her, she lied, the machine pegged out, and they had a post-test interview with her. In the post-test interview she admitted that she had leaked the information.
That's the way a polygraph examination trypically works. The real value is in the post-test interview when the interviewee is confronted with the polygraph results and asked to explain them.
