Case Study | Lie Detector Test solves security breach for high-level Manchester based client

How the other half live!

Our Manchester based client is definitely what you would call a “high value individual” operating a multi-national group of business and enjoying all of the trappings. His home was to say the least, palatial, with its own helicopter pad, indoor gym and swimming pool and extensive grounds including tennis courts.

When I arrived at the address I was immediately aware of the CCTV camera mounted upon one of the stone pillars which in turn supported a very impressive set of iron gates. I pulled up alongside the intercom fixed into the adjacent stone pillar and was about to speak into it when a voice echoed from within, welcoming me by name and inviting me to drive through the gateway. The iron gates slowly opened and I followed the driveway up to the impressive portcullis entrance and in to an inner courtyard. This place was seriously impressive.

I was met in the courtyard by an immaculately suited man, my first impression of which was he was ex-military and he obviously enjoyed the gym from the way he stood and filled the chest and arms of the suit. He directed me where to park and then accompanied me to the main entrance. Stood in the doorway was a woman who identified herself as the clients Personal Assistant.

The client had flown to Essex earlier that morning and although no apology was proffered for his absence his P.A. was extremely professional, quite clearly in charge in his absence and had prepared a full briefing file. She explained that the client had full time personal security wherever he travels and a permanent team of 6 security staff at his home. She stated that there had been certain concerns lately about confidentiality of their staff and wanted three particular security members to take a polygraph test.

When I asked why only three of the security staff were to be tested she detailed how professional she had been in checking on suspicions. The security team were professionals and highly respected by their employer who had recruited the team from a mixture of former UK, US, French and South African government security and services personnel. They had worked for their employer for many years.

Unfortunately, I am unable to reveal what the security breach of confidentiality was or how the suspects were narrowed down to just three of the team but what I can say is that the P.A. had done her homework and presented a very forceful case for suspecting one or all of the trio. It was interesting that all of the three employees had experience of being polygraph tested in the past, either by their government agency or services employers and they were at least outwardly, exhibiting support and trust in the polygraph process.

These guys were cut from the same cloth, regardless of their nationality. Each one was respectful with that air of confidence one has when you know your own capabilities, Interesting subjects to test. The P.A. waited patiently for the final analysis of all three examinations and seemed strangely accepting of the outcome. All three men passed the test.

I had in all honesty expected at least one of the examinees to fail the test. I had seen the briefing files on all three and had a long briefing with the P.A. but that outcome didn’t accord with my suspicions. I went into meticulous detail with the P.A. to explain the validity of the result but she offered no argument and was actually extremely grateful for my work. As we walked to the front door we were met again by the security officer who initially introduced me to her. Her parting words were that she would call and book the further tests once she had consulted with her employer.

A few days went by and I had almost given up on hearing anymore when the P.A. called again. Not to book a further test but to express her gratitude for an excellent job. I was a little surprised at her reaction until she announced that the confidentiality leak had been resolved, with one of the three who had not been tested having resigned his position. All of which supports two things that I was taught during my initial training all those years ago;

The polygraph moves in mysterious ways (when they run from the test there is always a reason). Trust your charts (trust the data that you gather and analyse).
