Ia specific incident known to have occurred. 35% of innocent examinees failed the polygraph, and overall correctness of classification obtained in this study was only 72%.

Mr. Webb:

Is the above 35% failure rate of innocent examinees correct in this "study?" If so, please explain how this study can be used on one hand to support the theory that counter measures do not work, but on the other hand not be an indictment of the accuracy of the polygraph?
