I was just watching Fox News' "On The Record" and a part of an interview with Deepac Scalpo, a suspect in Natalie Holloway's disappearance, was aired in which an investigator advised him that he would be foolish to not take the poly if he was innocent.  I am personally led to believe that he had something to do or knows what happened with Natalie and would like to see him brought to justice if he is guilty, but I just wanted to get some opinions on him taking the ploygraph.
