Interesting comment attributed to Assistant District Attorney Adrienne Lynch.
"Lynch argued yesterday that the court should not consider the results of the polygraph test - which supported Pring-Wilson's claim that he would not leave town. She said polygraphs "are not scientifically accurate," especially in predicting future occurrences."
Suppose she would have said "are extremely accurate" if the guy had failed it?
