Disadvantages of using a polygraph in investigations
It should be noted that everything listed below is not far-fetched, but objectively problematic, which will be confirmed by any experienced polygraph examiner specializing in this kind of research. We remind you that you can buy a professional polygraph from us at the manufacturer's price.
- A large number of suspects (tens - hundreds);
- Finding suspects in different places (districts, cities, countries);
- Lack of time for a full-fledged study (up to 1 hour);
- Limited time for investigation;
- Distracting employees for a long time from their official duties;
- Lack of a specialist in the region where the study is to be carried out;
- Borderline conditions that do not allow the qualitative use of a polygraph (stress, fatigue);
- Skillful countermeasures (psychological, physical, etc.);
- Finding suspects under the influence of pharmacological drugs;
- Refusal of suspects to take a polygraph test;
- The undesirability of disclosure by suspects of the circumstances of the crime;
- Refusal of suspects to cooperate with the investigation;
- Conflict of interest between customers and relatives, friends, colleagues;
- Conflict of interest between polygraph examiners and suspects;
- State and/or corporate ban on the polygraph's use;
- Difficulties in conducting research in languages that the polygraph examiner does not speak;
- Disadvantages of methods for using photographs in the course of polygraph examinations.
In addition to the general ones, there are also such economic restrictions on the use of a polygraph in investigating crimes.:
- Inexpediency due to the small amount of damage;
- Reluctance to investigate all suspects due to the high cost of polygraph services;
- Refusal to conduct research due to large amounts of associated costs for customers.
It is logical that in order to solve all these shortcomings, a “reliable assistant” is needed; - a new research toolkit or technology that would be mass and objective, simple and economical, universal and mobile.
And the technology already exists - "StimulTest" system, which over the past 7-8 years has been used more than 2000 times in investigations. As a result of such a long and massive testing, a specialized technique has been created to date, which maximizes the practical effectiveness of StimulTest, both in conjunction with a polygraph and without it, in the investigation of both administrative and criminal offenses.
Examples of effective use of StimulTest and polygraph
1 specialist - 54 suspects - 7 days - 1 crime - 1 criminal
The owner of the firm applied with an order to find out which of his 54 employees stole money from the office of one of the company's leaders. Within 3 days all employees were examined in StimulTest. As a result, a risk group of 5 people was formed. In the next 2 days, all employees from the risk group were tested on a polygraph. According to the result of two research methods (StimulTest + polygraph), on the 7th day after the order was received, an employee potentially involved in the theft of money was identified, which was subsequently confirmed by objective data (money balances and purchases made with the stolen money were found).
1 specialist - 137 suspects - 12 days - 1 crime - 5 criminals
At one of the wholesale warehouses, a safe with money located in the chief's office was stolen. Under suspicion were 137 employees of this warehouse. As a result of the study in StimulTest, a risk group was identified in the amount of 14 people. Subsequently, each of these employees underwent a secondary study in StimulTest using tests compiled personally for each of the suspects. As a result, 5 employees were identified who had the maximum probability of participating in a crime. As a result of subsequent testing of 5 employees using a polygraph, the likelihood of their involvement in the theft of the safe was confirmed. As a result of the investigative actions, the stolen safe was found, and a part of the stolen amount, which the criminals did not have time to spend, was returned.
1 specialist - 85 suspects - 10 days - 8 crimes - 12 criminals
From the owner of a sugar factory located in one of the regional centers, an order was received to identify the workers of the plant who were involved in the theft of 62 tons of sugar. There were 85 people under suspicion, who were remotely examined in 5 days by a specialist in the Stimul Test under the control of a responsible person at the plant. As a result, a risk group of 12 people was formed. Then the specialist came to the plant and interviewed all employees at risk, as a result of which 7 more episodes of sugar theft from the plant were identified. Further investigative actions objectively confirmed the involvement of 5 people in 7 thefts that occurred earlier. Polygraph studies of the remaining 7 employees from the risk group made it possible to identify persons potentially involved in the theft of 62 tons of sugar.
