ABSTRACT
In the 1990s, the Belgian Police found themselves confronted with a number of major criminal investigations they had been unable to solve. In order to force a breakthrough, they decided to submit suspects to lie detection tests using the polygraph. experienced polygraphers were flown in; from South Africa to test Flemish suspects, from Canada for suspects from Wallonia. The introduction of the polygraph in Belgium turned out to be successful. Not necessarily because the cases were solved by the polygraph per se, but because a number of suspects confessed during or after the test.1 Following these successes, the Belgian Federal Police in Brussels had their own people trained. Currently, three dedicated polygraphers test over 300 suspects per year.
