THE WORK OF MILITIA
Our militia was created by the working people to protect their rights. The officers of our militia have always displayed courage and heroism in the fight against enemies of our state during the Great Patriotic War as well as in the years of peaceful construction.
The main aim of militia has always been to maintain public order, to protect state and personal property and safeguard the rights of our citizens. Nowadays great attention in the work of militia is paid to prevention of crime, to its suppression. But if a crime has been committed, the militia officers are to solve the crime as quickly as possible. To fulfill these tasks the organs of internal affairs are composed of different departments.
The Criminal Detection Department is one of the most complicated militia services. The main responsibility of the officer of the Criminal Detection Department is to detect the criminal, that is to locate and apprehend him. In many cases the detective must trace a fugitive who is hiding.
The officers of the Criminal Investigation Department collect facts to prove the guilt or innocence of the suspect. The final test of a criminal investigation is in presentation of evidence in court Corpus delict8i must be established, the defendant must be identified and associated with the crime scene. The investigator must also provide competent witnesses.
Economic Crimes Department fights against those who don´t want to live an honest life. The responsibility of the officers of this Department is to reveal the criminal activity of those who commit embezzlement and other economic crimes, bring them to
justice.
