It was on ABC show last night. Did you see it?
I only saw part of it. There was a polygraph operator claiming that in this case, the polygraph was not accurate because the suspect had been subject to extensive interrogation BEFORE being polygraphed.
NEWS FLASH: The polygraph IS an INTERROGATION!
This case has already been discussed:
