Introduction to criminal investigation
Police liaison officers and plainclothes personnel are more or less a constant source of information. Despite legal restrictions, telephone eavesdropping and other electronic monitoring methods have become extremely important. Interrogating a criminal suspect is one of the most important tasks in criminal investigation. Experienced interrogators quickly analyze the characteristics of the suspect and use patience, strategy and psychological knowledge to get the cooperation or confession of the suspect.
In most countries, this procedure is very delicate, because confessions obtained in violation of the rights of suspects may be rejected by the court. The use of polygraph is also widely restricted by the court. Crime lab is more and more helpful to criminal investigation. These laboratories can handle a large number of physical evidence by using their equipment for chemical and other means of analysis.
Identification technology, especially fingerprint identification, newer voiceprint identification and DNA fingerprint analysis, plays a major role in modern investigation. Photography and microphotography, document identification, ballistics and other science and technology are still the standard criminal investigation methods. Forensic doctors can analyze blood and urine, and can identify traces of chemicals in the victim's body organs.
