The police authorities according to the new law of criminal proceedings

In this paper work there are analyzed provisions of the new Law of criminal proceedings referring to police authorities to take certain actions concerning previous investigation. New decisions are of the most importance: doing the DNA analysis in order to find out the identity of the suspect, hearing witnesses in cases when the public prosecutor gives the police the charge of doing it, taking palm prints from persons likely possible to have been in a contact with the things from the incident scene, then the police officials' right to direct the persons found on the crime scene to the public prosecutor and not to the investigative judge as it has been the case till now. The police has wider authorities by taking certain activities providing some proofs ( an investigation for all criminal acts and necessary giving an expert opinion without delay). In emergency cases, that is in cases where there is a risk of delaying, the police can take a photo of a suspect, then his fingerprints, order doing the DNA analysis and take all other actions necessary for providing a suspect's identity without previous the public prosecutor's giving charge of doing these activities. It is expected that it will contribute to the police work in previous investigation being more efficient. The public prosecutor has the priority in taking actions in previous investigation. The police has an authority to take these actions when the public prosecutor gives it the charge of taking them. The records referring to the suspect's hearing done by the police are not excluded from other records anymore and they can be used as an evidence in a criminal proceeding. The realization of particular actions can be done by using both audio and video recording machines. So, an audio or video record is added to the records or official notes. According to the new Law of criminal proceedings, for the first time, the police has an authority to organize taking a lie-detector test, that is a suspect's hearing with the usage of devices for registering physiological reactions of a person whose hearing is taking place as an activity exclusively in the competence of the police.
