Lie Detector Test Vancouver

[Concordia Zentner]

InFebruary of 1994, the FBI arrested Aldrich Ames, who had been a CIA employee for 31 years. Ames was arrested and charged with espionage. He was a Russian spy. For nine years, he had been passing secrets to the Russians in exchange for over $1.3 million. His spying activities had compromised dozens of CIA and FBI operations. Worse yet, his treacherous crimes had led to the deaths of several CIA spies and the imprisonment of many more.

During the time that Aldrich Ames was operating as a Russian spy, the CIA had twice given him a lie detector test. Despite having no special training in how to defeat a lie detector test, Aldrich passed both times.

The theory behind the polygraph is that when people are lying, they experience a different emotional state than when they are telling the truth. Specifically, it is thought that when people are lying, especially in high stakes scenarios such as police interrogations, they are anxious or afraid of being caught in a lie. When guilty people are asked questions that would reveal their guilt (e.g., Where were you last Tuesday?), and they lie, the fear of being detected causes increased activation of their sympathetic nervous system. This activation leads to an increase in heart rate, blood pressure, respiration, and perspiration. These changes are part of the fight-or-flight system that initiates whenever was are scared. You have probably felt your heart pounding or your palms sweating when faced with danger, be it a vicious dog, an angry boss, or an upcoming exam.

The polygraph is used in criminal investigations, although it is generally not admissible as evidence in a trial. It is also used as a pre-employment and continuing employment screening tool for many federal employees who work in sensitive positions, such as CIA agents and FBI agents. Private businesses, however, cannot force their employees to submit to a polygraph test.

So, does the polygraph actually work? Are the results accurate? It does work much of the time. Typically, when someone is lying, a well-trained polygraph examiner can tell. It is not 100% accurate though. The American Polygraph Association is the world's leading association dedicated to the use of evidence-based scientific methods for credibility assessment. It is an organization whose members are largely polygraph examiners. They estimate the accuracy of the polygraph to be 87%. That is, in 87 out of 100 cases, the polygraph can accurately determine if someone is lying or telling the truth.

For more clear evidence that the polygraph is unreliable, just look back to the Alrich Ames case mentioned at the top of this article. Ames lied during his polygraph examinations at the CIA, and he passed each time. In this case, the lie detector test failed. When asked how he passed the polygraph test, Ames said that he followed the advice of his Russian handlers. They told him, "Just relax, don't worry, you have nothing to fear." The Russians knew that the polygraph was flawed. They knew that it was only accurate if the examinee was worried and anxious. They knew that if Ames could just relax, he would pass.

It takes all of us to help protect our public drinking water system. The City of Vancouver appreciates your assistance in protecting our drinking water system by installing, maintaining and testing backflow assemblies. Please ensure your state approved backflow prevention assembly is properly installed and tested.

Once your account becomes non-compliant, we provide a courtesy phone call notifying you that we have not received a passing backflow assembly test report. A fourth notice is generated notifying you that in 15 days a $250 fine will be assessed on your water utility account. A fifth notice will be generated notifying you that the $250 fine has been assessed on their water utility account and if after 60 days we still have not received a passing backflow test report, a fine of $500 will be assessed on your water utility account. If we do have receive a passing backflow test report by the due date of the fifth notice, a sixth notice is generated notifying you that a $500 fine has been assessed on their water utility account and in 30 days a $1,000 fine will be assessed on your water utility account and water service will be terminated until your account becomes compliant.

Certified backflow assembly testers: If you would like assistance in determining the service area for the backflow assembly test that you are performing, please contact us for a copy of our water system map.

These assemblies, when properly maintained, will stop potentially hazardous water entering the potable drinking water system when backflow occurs. Installation requirements vary for residential and commercial properties, depending on the water use and assessed health hazard.

Washington State Law (WAC 246-290-490) and Vancouver Municipal Code (VMC 14.04.155) require annual backflow assembly testing. There are internal operating parts that are susceptible to wear and failure. Annual testing ensures that the assembly is operating properly, safely protecting our drinking water system. Property owners are ultimately responsible for scheduling and completing backflow assembly testing requirements.

For single-family residential customers, the following chart determines when your backflow assembly test is due. For larger residential and commercial accounts, the due date is the 1st of the month agreed upon when the account was established.

The City emails and sends letters to property owners, tenants, and property managers notifying of the responsibility to schedule and complete the backflow assembly test(s). Please coordinate to schedule the backflow assembly test(s). We mail up to three notices before account(s) become non-compliant.

Our new backflow software will not allow us to grant extension of backflow assembly test(s). If your backflow assembly test(s) fails, the repairs and retesting must be completed by the due date of your backflow assembly test(s). Please schedule the backflow assembly test as soon as possible. Multi-family and commercial customers may request an extension of the backflow assembly test(s) by contacting the Water Quality office at backflowt...@cityofvancouver.us or 360-487-8276.

Although we do not see any of the backflow assembly testing fees, we have found that generally a residential backflow assembly test will cost between $35 and $75. The average cost of the backflow assembly test is around $50.

Your backflow assembly tester should provide us a signed copy of the test report. You should also receive a copy of the test report for your records. In case the test report is not received by our office, you can send us a copy of your report, if requested. If your test failed, contact your backflow tester for repairs and subsequent retesting of the backflow assembly.

Please give your tester time to fill out and submit the report. We receive reports electronically, by mail and in person. We try and enter all reports before mailing out reminder notices. There could be times when notices are received during the same time notices are mailed. There may be multiple backflow assemblies and a new tester may not test them all. Check with your tester to request that they send us a copy of the test report.

Yes, the backflow assembly is there to prevent contaminants from entering the potable water supply which are there whether or not you are using your sprinkler irrigation system. If you decide to abandon your sprinkler system, your backflow assembly can be removed. Email the Water Quality office at backflowt...@cityofvancouver.us or call 360-487-8276 and we can outline the process.

The "fruit machine" was a battery of psychological tests developed in Canada by Dr. Frank Robert Wake,[1] a psychology professor with Carleton University[2] in the 1960s. It was hoped that Dr. Wake's research program would be able to help the Government of Canada identify gay men working in the Public Service or to prevent gay people from obtaining government jobs. The subjects were made to view erotic imagery; "homosexual words," as well as an early form of lie detector to measure perspiration and pulse. The so-called machine was supposed to measure the subject's pupil dilation (pupillary response test), in response to the erotic images and words. The crude apparatus was constructed by the RCMP's Identification Branch.

The research program was employed in Canada between 1960 and 1964-ish as part of a campaign to eliminate all gay men from the civil service, the Royal Canadian Mounted Police (RCMP), and the Canadian Armed Forces (CAF). Thousands of Canadians lost their jobs or resigned and many died by suicide. Although funding for the project was cut off in the late 1960s, the RCMP investigations continued, and the RCMP collected files on well over 9,000 people.[3][4]

The machine used a chair similar to that used by dentists. It had a pulley with a camera going towards the pupils, with a black box located in front of it that displayed pictures. The pictures ranged from the mundane to sexually explicit photos of men and women. It had previously been determined that the pupils would dilate in relation to the amount of interest in the picture, in a technique termed "the pupillary response test".[5]

The functional mechanism of the "fruit machine" was pseudo-scientific, and its results inaccurate. First, the pupillary response test was based on fatally flawed assumptions: That the chosen visual stimuli would produce a specific involuntary reaction that could be measured scientifically with 1960s technology; that homosexuals and heterosexuals would respond to these stimuli differently with enough frequency to sort them; and that there were only two types of sexuality.[6] One physiological problem with the method was that the researchers failed to take into account the varying sizes of the pupils and the differing distances between the eyes.[5][6] Other problems that existed were that the pictures of the subjects' eyes had to be taken from an angle, as the camera would have blocked the subjects' view of the photographs if it were placed directly in front. Also, the amount of light coming from the photographs changed with each slide, causing the subjects' pupils to dilate in a way that was unrelated to their interest in the picture. Finally, the dilation of the pupils was also exceedingly difficult to measure, as the change was often smaller than one millimeter.[5]
