The Reader's Matt Potter today (Aug. 28) tried unsuccessfully to get San Diego polygrapher Paul Redden to talk about his financial relationship with Lafayette Instrument Co., a maker of lie detector devices.

Redden purportedly gave local politician Carl DeMaio a lie detector test about the story of his masturbation in a men's room. DeMaio claims he passed the exam.

On May 20 of this year, McClatchy's Washington bureau ran a comprehensive investigative piece on the financial ties of government officials and Lafayette. The article, which noted that scientists consider polygraph testing unreliable, cited several examples of tie-ins, such as police employees being salespeople for Lafayette.

The McClatchy article noted that Redden had been listed "as a [Lafayette] dealer since at least 2007 and last year was identified as a salesman in at least one of San Diego's purchases from Lafayette. The police department refused to answer questions about Redden, including when he'd worked there or whether he now works as a contractor. San Diego has been buying Lafayette polygraphs since at least 2002 when it awarded a noncompetitive bid to the company," said McClatchy.

Matt Potter posted an article in the Reader about the McClatchy story on May 28. Then again today, he called Redden, who refused to answer questions and terminated the conversation.

Obviously dodging to hide a fact. Professionals can give an honest answer if the answer is an honest one.

shirleyberan: A number of scientists point out that guilty people can pass polygraphs and innocent ones fail. Best, Don Bauder

Personally, I feel that polygraph tests are junk science. The machine, the “expert” and the whole experience of being questioned is a show. There are numerous texts about how to beat the test (sometimes using drugs) and numerous studies debunking the devices. From what I understand, they can only be used in Federal court when both the defense and prosecution agree.

I have read that pathological liars have no problem passing polygraph tests because they psychosomatically restrain their physiological responses to challenging questions.

Ponzi: I have heard that sociopaths con themselves into really believing that they didn't commit a heinous crime that they did commit. Best, Don Bauder

But why didn't police department just answer McClarty's question about Redden? Protecting a polygraph peddler? I wouldn't rely on A Lafayette. Like to see Carl on Dr. Phil and pass his polygraph guy, not gonna happen.

shirleyberan: Excellent question. Why didn't the local police cooperate with McClatchy? It is one of the most respected news organizations in the country. Best, Don Bauder

maybe his passing the test tells more than he wants the public to know about his psychology lying

Murphyjunk: This morning, DeMaio came out with a statement on how truth is so important in San Diego. I could hardly stop laughing. Best, Don Bauder

I may have to avoid that speech on the evening news, I may not be able to stop a laughing fit.
