First, the basic level: this article is actually the most basic prerequisite for engaging in detective work-this article is not suitable for this industry if it does not meet the basic standards! It mainly includes: basic knowledge of social life, general understanding of business, industrial enterprises and economic affairs, intelligence beyond the average level of society, education level and healthy body.
Second, professional knowledge and technology: practical legal knowledge, rich social common sense, familiar with the general operation process and essentials of enterprises and government functional departments; Mastering various professional skills, such as driving, photography (including secret photography), general skills of interrogation and inquiry, observation, memorization and basic self-defense ability, is the most obvious difference between trained detectives and ordinary people. Only by mastering these professional knowledge and skills can we effectively engage in all kinds of work and become a qualified detective!
Third, professionalism and comprehensive ability: the so-called professionalism is the professional consciousness and highly personalized ability formed by a person who has been engaged in a certain job for a long time. It has something to do with professional skills, but it is not as specific as the technology itself, and it is more reflected in softer things such as consciousness and feeling. Like comprehensive ability, it is difficult to cultivate and train directly, and it always depends on sudden enlightenment after long-term practice, but it is all the time. Whether you have these qualities determines whether a detective can stand out-become an excellent detective! 1. Feeling: In practice, detectives face a complex world, and the information they have to face is complicated and confusing. Insight is a special kind of "eyesight", which allows detectives to quickly grasp the key points of the problem in this complicated and confusing appearance! With it, we can simplify the complex and find out the key problems and root causes. 2, comprehensive thinking ability: mainly including generalization, organization and practical analysis and reasoning ability! The ability to summarize and organize enables people to quickly digest and thoroughly understand relevant information, while the ability to analyze and reason enables people to understand the essence from the phenomenon, find out the root of the problem and propose solutions! 3, macro grasp ability: that is, strategic thinking ability! Mainly refers to a thinking habit of grasping and analyzing things from the overall development trend and joints of things! For senior detectives in charge of leadership and command, this quality is essential!
Fourth, personality quality and psychological quality: the so-called personality determines fate! Seriously! I have discussed how to be a detective, what qualities a qualified detective and an excellent detective must have! So here, personality quality and psychological quality are the key to determine whether a detective can become a truly excellent detective! Here, I mainly define the detective's personality and psychological quality as: initiative: this article cannot be overemphasized! Detectives are faced with all kinds of difficult tasks, and it is difficult to make a difference without a spirit of always moving forward and never giving up in the face of difficulties! In addition, in specific work, all kinds of clues and possibilities are scattered in every corner of society. Without a strong and active consciousness to collect and grasp, waiting is impossible to gain something! Adventure and courage: for detective work with great personal danger, it is obviously impossible to carry out the work effectively without certain adventure and courage! Flexibility: this is mainly reflected in thinking and adaptability! Sometimes it is said that detectives have a lot of ideas, and they can always see places that others can't see and come up with some unexpected ideas. In fact, detectives are better at observing and analyzing problems from different angles and positions! The flexibility of adaptation is more reflected in a so-called wit, which can quickly discover, adapt to new situations and respond. Perseverance: To some extent, it is different from initiative, and more reflected in endurance in adversity.
The so-called big things, pioneering ability, coping ability and patience are essential! If the first two mainly refer to coping with prosperity, opportunities and daily situations, then the latter mainly refers to the qualities that a willing person must possess in adversity! Sense of justice: although this point is listed at the end, it does not mean that this point is the least important! As a profession that often contacts with the dark side of society, detective has a strong sense of law and justice, which is the key to ensure that he "never gets wet when walking by the river"! If there is no sense of justice, what is the difference between a detective and a "gangster" who usually gives money to eliminate disasters? ! ....................................................................................................................................................... Undoubtedly, ...........................'s learning style is integrating theory with practice, which is consolidated through case teaching and interactive discussion! Therefore, this paper mainly takes the course "Detective Common Sense" as an example to refine the topic for the reference of interested friends! Detective history: the earliest detective, the social, economic, technical and cultural background of detective, the comments of famous detectives, the review of the basic development of detective industry, and the present situation of detective industry in contemporary western countries;
The emergence, history, present situation and prospect of Chinese mainland folk detective agencies: the emergence and present situation of investigation and credit reporting agencies in Hong Kong and Taiwan! Practical legal knowledge:
1. Basic laws and regulations: criminal law, criminal procedure law, regulations on administrative penalties for public security, lawyer law and rules for lawyers to handle criminal cases, anti-unfair competition law, consumer rights protection law, product quality law, general principles of civil law, civil procedure law, contract law and company law; Trademark law and patent law; (mainly the part directly related to the investigation)
2. Relevant procedural essentials of contact with relevant institutions and organizations: for example, contact with public security organs, industry and commerce, technical supervision departments in counterfeiting cases, cooperation with lawyers in pre-litigation evidence investigation, and information contact with various government agencies and professional groups; Because this part will also involve the training of project investigation methods later, here are just some basic procedures-as for the production of various documents, who to look for from various organs, the essentials and so on. They are not involved here! Methods and means of investigation: survey introduction, general channels and means of investigation (inquiry, data retrieval, on-site observation and analysis, collection and entry, etc.). ), investigation methods of various projects (intellectual property infringement investigation, pre-litigation evidence investigation, collection and analysis of background information of target company and personnel, anti-fraud investigation, investigation of missing persons, collection and analysis of business intelligence, etc. ) communication knowledge of detectives: detectives should pay attention to the importance of daily communication and how to analyze the environment. How to meet different types of people (civil servants, businessmen, scholars, journalists, editors, factory workers, community service personnel, housewives, white-collar women, etc.). On different occasions, through different ways (clubs, clubs, sports fields, work contacts, etc.). )-This course briefly introduces the methods and essentials, and specifically analyzes the actual situation and psychological needs of the target object, as well as the occasions and people contacted.
Information collection and analysis: the concept of intelligence, basic information retrieval tools and skills, the introduction of important databases and databases, and the collection of specific information by personal network. Common sense of safety precautions: safety awareness that should be cultivated (such as quickly judging the occupation, experience and intention of people around you; Get into the habit of reading and memorizing license plates, house numbers, shop signs and telephone numbers quickly. Pay attention to cultivate a sense of direction and orientation, and keep a clear sense of orientation about the area you enter, the passage of the building, the layout structure, etc. ), the safety precautions when going out to communicate with people, the safety points when staying outside, walking, taking a bus, taking a boat and driving, the basic common sense of anti-tracking, monitoring and counter-terrorism, and the main points of preventing and handling kidnapping and robbery.
Tracking and anti-tracking training
Familiar with the basic terrain:
1, familiar with the basic situation of the city's main traffic lines, subways, buses and taxis.
2. Select several shopping malls and buildings with multiple exits for key familiarization-entrances and exits, employee passages, underground parking lots, etc.
3. Be familiar with parks, sports fields and other places, and choose the appropriate dead mailbox delivery point.
4, familiar with the main entertainment venues, cinemas, choose the right joint location.
My opinion on tracking and anti-tracking training mode:
I. Purpose:
Through practical tracking and anti-tracking, the students of both sides are trained in psychology and skills in almost actual combat. Through comments and interactive discussions afterwards, the students can not only fully master various practical techniques such as tracking and anti-tracking and their safety precautions, but also learn to sum up their own experiences and lessons and cultivate their ability to work and study independently.
Second, the conditions:
1. personnel: divided into two groups-stalker trainees and stalker trainees;
The former has only two or three trainees, and generally needs to have such work experience, and it's not that the trainees don't know! Otherwise, you should make up properly; The latter usually only arranges one person;
Two cameramen are responsible for filming related processes, overall scenes and key links (such as the check-in process of the tracked students) for post-event summary and comments, and can also select highlights as teaching models for novice training in the future.
2, equipment and tools:
Tracker and tracked trainee: each person is equipped with a watch, a wig, a makeup toolbox and a miniature spray gun with dye inside.
Photographer: Close-up Close-up Close-up photos of miniature cameras and digital cameras for long-distance photography.
Third, the location:
Generally arranged in the most typical places: buses, subway stations, large shopping malls and office buildings, urban roads and their lanes.
Four. Procedures and specific operation methods:
According to the instruction, students must arrive at designated places distributed in designated bus stops, subway stations, shopping malls and office buildings (all need to sign in at the places they know or temporarily designate), and finally arrive at the target place to collect or hand over specific articles and documents.
Before the confrontation driller arrives at the first designated place, he starts tracking from the starting point or any road section, holding the photos sent to his trainees, and each approximate destination can be informed in advance, but the specific sign-in place of the trainees is unknown to the confrontation driller in advance, and can only be known by tracking the trainees. During this period, the anti-driller can also carry out simulated attacks (mainly simulating the attacks of poisonous needles and knives) without being discovered by the trainees. The methods are as follows: when simulating the poison needle attack, you can shoot the trainees with a miniature concealed water gun filled with dye; Simulated knife attack can touch some inconspicuous but hard-to-find dyes on the hands, and can directly touch any key part of the body after approaching the students-since the hands can reach it, it is even more no problem to use a real knife in practice). After the attack is carried out, both sides should leave immediately and continue to complete their respective instructions.
During the whole process, students should pay attention to the number, physical features and clothes of people who are considered suspicious in each link. When it is determined that a trainer is carrying out a simulated attack on himself, you can leave a mark on the suspected attacker with a miniature spray gun (only storing dyes that can be fired several times)! After confirmation afterwards, you can add points or reduce the number of successful attacks.
Verb (abbreviation of verb) evaluation and evaluation:
1, assessment mainly depends on three indicators:
First of all, the number of times the trainees of the tracked party found the trainees of the tracked party and the accuracy of their appearance and clothing description! Because stalkers appear in several places indefinitely, and change clothes or even hair styles every time, it is fair to confirm the effectiveness of each discovery according to the total number of times that trainees find stalkers and the accuracy of appearance and clothes description-it can effectively evaluate trainees' alertness, observation and judgment ability and memory; The more effective the stalker is, the lower his evaluation score will of course be.
The second is to see if the trainees of the tracked party can effectively get rid of tracking. Because in this training, the trainees have to go to several designated places, and the specific sign-in place of the trainees is not known to the tracker, which also provides a space for the trainees of the tracked party to display their skills! As long as the tracker fails to accurately record the exact place and time when the students sign in, the students of the tracked party can get a large bonus in the evaluation. Otherwise, stalkers will be severely punished.
Finally, it depends on how many times the students from both sides have successfully attacked! A student who has never "died once", only died two or three times, or has made a strong counterattack against the attacker, is definitely much better than those students whose clothes are spotted! In the same way, a stalker who kills the target countless times without leaving a trace on his body is undoubtedly excellent in tracking approach skills and psychological quality of "one foot in the door"!
Some basic knowledge of detectives
First look at the types of fingerprints:
First, obvious lines: that is, visually visible lines.
2. Line formation: refers to fingerprints found on soft substances, such as candles and clay.
Third, the latent pattern: it is a fingerprint network formed by human natural secretions such as sweat and transfer, which is not easy to find with the naked eye and is the most common fingerprint.
Here are several ways to collect hidden lines.
If fingerprints are left on the surface of non-absorbent objects such as metal, plastic, glass and ceramic tiles, the inspection method is easier.
There are two methods: one is to choose powder with large color contrast without using powder, and scatter it on the surface of the article to extract a complete fingerprint.
Second, magnetic powder method, using fine iron powder particles, using magnets as brushes, brushing back and forth to show fingerprints.
If fingerprints are left on the surface of absorbent articles such as paper, cards, leather and wood, they must be chemically treated before they can appear in the laboratory. The following are several commonly used chemical methods:
1. Iodine fumigation: that is, iodine crystals generate steam when heated, which will react with the grease left in fingerprints, and then yellow-brown fingerprints will appear.
2.Ninbydrin method: When the reagent is sprayed on the sample, it will react with the amino acids in the body secretion, and purple fingerprints will appear.
Third, silver nitrate method: after silver nitrate solution reacts with sodium chloride in latent fingerprints, black fingerprints will be produced in the sun.
Fluorescent reagent method: Fluorescent ammonia and phenylglyoxal react with protein or amino acids of fingerprint residues almost immediately, resulting in highly fluorescent fingerprints. The reagent can be used on the surface of colored articles.
Smoke reflection:
The formation of smoke reaction is because in the first stage, the gunpowder in the shell casing at the contact position of the bullet is ejected with the bullet.
The smoke of a revolver is sprayed into an umbrella: a classic gun type-Smith Wei Sen.
The automatic smoke is sprayed into a downward semicircle: a classic gun type-Bailette.
In short, the response to smoke removal is to remove the gunpowder attached to the body, change clothes and shine shoes.
If we don't take corresponding measures, the powder residue will remain on us all the time.
As for checking the smoke reaction, the general police will be equipped with test paper to test the smoke reaction when they are on the scene. The principle is simple. The smoke reaction can be easily checked by replacing nitrate with a metal compound that is more active than nitrate.
