Infiltration into the criminal milieu

The characteristics of the modern organized crime have demanded the properly organized competent authorities in order to be able to oppose it successfully. It cannot be achieved without the infiltration into the criminal milieu as a complex criminal-operating activity. It is also a postulation for the competent authorities being engaged in a prevention and combating crime to strive to provide reliable sources of information in the criminal structures, with the aim of detecting the intended or committed criminal acts as well as collecting the evidence of their perpetrators’ guilt. Nowadays, it`s almost impossible without an “insider“ to reveal the structure of the criminal organization, the committed and planned crimes, having in mind extensive protection measures taken by its members. The changes themselves in the manifestation of the organized crime have gone beyond the mere use of informants and made a need for developing the new investigating techniques, aimed at the infiltration into the criminal milieu, which includes the usage of the undercover investigators in order the conspiratory investigations to be conducted and the simulated activities to be realized.
