How did the grandfather fail the lie detector tests on Dr Phil Fiday?

if he failed the test..he lied period.

He failed them because he is sick and he really did molest all those people but is too scared to admit it, even though everyone knows he is lying.

arrgh, i missed the fridays episode!!! what happened??

what most people are not aware of is that if you are on ANY kind of medication or if a female is on her period the results will show inconclusive or false returns. Beings as he was a previous offender, this will also affect his results because just speaking of his past brings changes in the pulse and respirations. Being as he is an older man, he more than likely takes Some Form of medication. All meds must be cleared out of system and a week must have gone by after a females cycle. Also if you have any mental conditions you have have false results, Good and Bad, false results. This man is a pediphile admittingly so. He will have alot more to answer to after the show.
