Briefly describe the connotation of the object of investigation research

Investigation is a comprehensive applied science that studies the laws of crime and the methods of exposing and verifying crimes. Investigation is the opposite of crime, and there is no investigation without crime. However, in the case of crimes in the broad sense, there may not be investigation when there is a crime.

This brings us to the question of how crime is defined. In other words, crimes in detective science are crimes that are actually criminal. The law of crime does not refer to the law of criminal phenomena as a whole in criminology, but refers to the law of individual cases or series of cases.

Exposing and verifying crimes is not only an important part of investigation work, but also the focus of investigation research. Here, it is necessary to pay attention to distinguishing the difference and connection between the work object and the research object. At the same time, since it is called science, it refers to a kind of science, and this study is of course scientific, although it is divided into arbitrary investigation and compulsory investigation in terms of measures taken.

Among the two major characteristics of investigation, the legal and scientific nature of investigation, the investigation work emphasizes mandatory, while the investigation research emphasizes its scientific nature on the premise of not excluding the legality, and it is only an applied science.

Research objects of criminal investigation: 1. To study the history and current situation of criminal investigation in China, and to continuously explore the regularity, characteristics and trends of criminal activities.

2: Study investigative countermeasures to combat criminal offenses. 3：

Study the subjective and objective reasons for the success of criminal offenses, and formulate measures to prevent crime. 4. To study the theories, experiences and techniques of criminal investigation in other countries, so as to enrich the content of criminal investigation in China and improve the level of criminal technology.

The principle of investigation guides investigators to fully investigate and use the traces of the scene in the investigation process, determine the suspect and the direction of investigation through the obtained physical evidence, and finally restore the crime scene and crime process to complete the case detection.

The principle of material exchange indicates that the criminal must have contact with the scene and carry out material exchange, and there must be traces left. Therefore, it is necessary to protect the scene and fully search and collect evidence at the scene.

The principle of the same identification: all kinds of evidence obtained at the scene, some of which can be used to certify that the suspect is the person who committed the crime at the same scene. For example, DNA, fingerprints and other typical identifying characteristics can refer to the unique person who testifies to the perpetrator.

Some evidence may become important evidence to support the investigation of a case as technology develops (e.g., DNA evidence was not available for many years).

The principle of crime reproduction is a basic principle of investigation science formed by introducing the three modern theories (system theory, information theory, and cybernetics) into the field of investigation science, and scientifically abstracting and summarizing the process and essence of criminal case detection. According to this principle, the investigation of criminal cases is a systematic project regulated and controlled by the main body of the investigation. The process of solving a criminal case is essentially the process of acquiring, processing, and exporting criminal information in order to reproduce the facts of the crime.

The principle of causality, various evidence in the process of investigation can point to a chain of causality, which can analyze the motive of the crime and the entire criminal process.

There's not much use in reconnaissance right now, so let's feed the fish all the knowledge you learn in school.

Modern times are all about evidence.

Skynet monitoring without dead ends;

the supervision of the population by the hukou system;

high-tech collection of various traces;

control of network information;

Informants and reports that are worse than spies.

Whether you admit it or not, modern reconnaissance is like that.

The Sherlock Holmes set is outdated, but the news still says it.

From the perspective of discipline genealogy, in the disciplinary dimension of science and engineering, investigative behavior is a kind of engineering behavior, investigative thinking is a kind of engineering thinking, and reconnaissance is essentially an engineering discipline. Investigation science should have characteristics and temperament that distinguish it from other theoretical disciplines: concrete, open, technical, valuable, integrated, and integrative.

Investigation is an independent legal discipline, which constitutes the three pillars of the criminal law system, together with criminal law and criminal procedure law.

Law degree of a criminal legal nature.

There are several opinions in the academic community:

1) Criminal investigation belongs to law (criminal law, marginal law or applied law);

2) Criminal investigation belongs to public security;

3) Criminal investigation is criminology;

4) Criminal investigation is a comprehensive discipline of social science, natural science and technical science.
