Polygraph testing used to play games in Detroit murder case

Lawyer: Bob Bashara passed second polygraph test

Bob Bashara passed a privately administered polygraph examination Wednesday night, indicating he had no involvement with his wife’s murder, his defense attorney David Griem said this morning.

Griem said his polygraph examiner — whose name he would not disclose — told him “that in his opinion, Bob did not have anything with the death of his wife.”

Griem said the second test was given to counter reports that Bashara failed a polygraph performed for the Grosse Pointe Park Police.

“If the prosecution wants to have a battle of polygraph examiners, we will,” said Griem, adding that he does not believe the person who performed the test for police is licensed by the state of Michigan.

The conflicting results underscore why such tests are almost never used in court, Griem said.

“There’s a reason they’re not admissible,” he said. “The results are often more subjective than objective.”

Then why do them? You end up arguing over nonsense.[Polygraph]

A National Academies report said this:

Almost a century of research in scientific psychology and physiology provides little basis for the expectation that a polygraph test could have extremely high accuracy.

The theoretical rationale for the polygraph is quite weak…

Research on the polygraph has not progressed over time in the manner of a typical scientific field. It has not accumulated knowledge or strengthened its scientific underpinnings in any significant manner.

And concluded it was not an appropriate tool for screening individuals who may post threats to national security. It’s also appropriate in the murder case above for the same reasons.

    It is used by investigators as a means to force the hand of a suspect they “believe” may be guilty but do not have enough evidence to proceed directly to charging. Law Enforcement view investigations as a form of high-stakes poker game by using misdirection and bluffing. It is kind of sad that the investigation process in this country has come down to using these methods as well as tainting the public jury pool before hand by releasing info to the public prior to any charges being filed. They tried to do this with the Casey Anthony case and look what happened there. It seems they still will put thier money on the public being stupid enough to believe everything the state wants them to. Including the famed, truth-telling, mythological beast “Polygraphicus.”

    How exactly do they try to work the finesse, so to speak? If you refuse they leak that to the public and humiliate you, and if you take it but fail they badger you and put pressure on so you’ll confess?

    If you are accused of a crime you didn’t commit, or are a suspect or person of interest, and the police ask you to take a polygraph test, should you decline?

    Yes. You should decline. It’s a no win; the odds are better that you will show a false positive and they can use that against you.

    Also the results are never shared during your “interview” they are given to the detectives whom then diseminate the info. Since the only person “qualified” to interpret the data is the Polygrapher, and he is employed by the state, the detectives can use it any way the want. I am not saying this guy is innocent I am commenting on the tactics and lack of actual investigation anymore. ALWAYS SAY NO! Because they will release the fact you declined, or failed, rarely that you passed and usually will not tell you and your council the truth during the initial interview after the test. It is a a catch 21 designed to pressure you into dealing if you are guilty and sometimes when you are not. It is all about the conviction.
