Frame metallodetectory designed to ensure the safety and screening of people passing into the territory of the organization owning (leasing) data detectors. Based on the analysis of articles and interviews, we can distinguish two main groups of facts concerning equipment and people, as well as some general characteristics of the current situation. The Moscow Metro consists of about 300 stations, each of the station’s lobbies is equipped with metal detectors, some conclusions can be drawn from sources. Moscow, St. Petersburg and Nizhny Novgorod metros are equipped with SmartScan C18 frame metal detectors, according to the characteristics given on the official website (and the statements of Dmitry Basov, owner of Modern High Technologies,) this model has software that suppresses electromagnetic interference that distorts the results of the detector. The program allows you to control the level of sensitivity to the amount of metal and visualizes the zones (18) of the intended location. However, it does not allow to identify the object (gun, knife, keys, telephone, etc.). According to the technical characteristics of the frame, it’s parts should have a distance of 1 meter between them in order to operate correctly. However, observing and assessing the reliability of the above characteristics point to a number of facts (some characteristics are also key in a security scenario). In many cases (at shallow stations) the frames react to trains passing under them. In addition, in most cases the frames are installed with distances of less than 1 meter between them, so they can potentially distort each other’s work. Situations where frames are banal are not uncommon. The frames have, in addition, to the visual, sound identification of metal detection, however, (at least during peak hours) the sound is muted, since with an intense flow of people it does not carry useful information. Since the established frame is not capable of recognizing objects, with a dense stream they are not able to identify a person with a firearm. Nevertheless, including due to their reactions to metal clusters, every day security officers find 150- 200 dangerous objects (traumatic, hunting weapons, etc., not necessarily carried with a destructive purpose). However, given the fact that in 2015, inspectors checked almost 17 millions of people and 9 million pieces of luggage, and only 2.4 billion people were transported last year, the figures are not comforting: based on these data, approximately 64,000 dangerous items were found during the year, while approximately 1/140 passengers were inspected. An even more serious problem is that the framework does not respond to explosives. Taking into account the fact that it is not illegal to carry a bucket of hardware (which is the main striking filler of bombs), the components of a bomb RESEARCH STAGE can be carried separately, and then assembled. To detect explosives, there are gas analyzers at the stations, the reliability of which, however, is in doubt due to the strong air flow. The stations are also equipped with special equipment for suppressing radio lines controlling explosive devices (their reliable usefulness remains undetermined). In addition, there are x-ray scanners for baggage inspection (in fact they are the most effective means, as they are able to detect even plastic weapons, moreover, there are similar installations (including domestic production) that allow inspecting a person, even without removing the outer clothing, it takes a few seconds). The location of the framework clearly indicates that their purpose is also to narrow the aisles and slow down the flow of people to facilitate the processing of information coming from the framework, but this is not a solution, since it creates congestion in front of them and nothing can prevent the terrorist from blowing up a bomb in the resulting mass of people (in the period 2012-2015, 39 people died from terrorist attacks in transport, 23 while passing through the frame). An integral part of the security system are the operators of the frame and other equipment — security staff. There are also a number of significant problems. Private investigation in 2015 showed that the checks were formal, the security staff sought to fulfill context studying. the analysis of official open sources the plan, log entries of inspected people (30 per hour). Many workers do not look at the frame, and sometimes they are not competent in administrative legislation. However, the main problem (partly the cause of the above) is a shortage of people. As well as the need to systematize their work. For optimized work and greater employee efficiency, more people are needed. To ensure a sufficient number of employees (5 instead of 1-2), it is necessary to allocate about 2 billion more, otherwise the frame is in fact useless, due to the lack of operators. In addition, systematization of the workflow is necessary, alternating changes in the activities of employees, in order to avoid dispersing attention, as well as creating systematic dynamics in the security system, it is necessary to create more comfortable working conditions (instead conditions for rest, although this goes without saying). It also does not facilitate the work of employees surrounding space. At many stations, in conditions of intense flows of people, employees are simply not able to squeeze through the flow of passengers and stop a potentially suspicious person to inspect. The choice is subjective, in addition to this, employees are guided by one clear instruction: to pay attention to people with large bags (and behaving suspiciously). All employees took refresher courses, attended the course “Culture of passenger service” and “Profiling” (a set of psychological methods and techniques for assessing and predicting human behavior). However, without constant practice and deep immersion in this method, it is impossible to achieve real results, since there is no universal approach for analyzing people’s behavior. Despite the conventionality of the practical benefits of passing the “Profiling” course by security officers, the movement in this direction is extremely promising. Thanks to this technique, it is possible to identify a person with destructive intentions. A person is much better than a machine can determine whether a person is dangerous or not. Since terrorist organizations, using recruiters, are looking for a certain psychological stock, taking into account modern technologies, it is possible to compile a risk register, which could significantly increase security. Since the bomb can be carried through in parts, inspections without an identity document are useless, only personal identification, provided the registry exists in the access of the staff, could give an adequate assessment of the situation. In addition, if we talk, for example, of railway trains (in fact, the metro too), to commit a terrorist act it is not necessary to blow up the train, there are tens and hundreds of kilometers of railway tracks. For the reasons listed above, specialists and passengers are skeptical about the framework (several successful attacks play a role), according to experts, not one prevented attack is known (thanks to the existing system). There is another function of the frame and security officials, it is to create psychological pressure on potential criminals. Creating the appearance of protection, there are cases when a man in the form of a frightened single terrorist, and he abandoned his plan, but not a fanatic or a professional. Preventive (deterring) measures (due to the presence of frame metal detectors and employees in the form) taken publicly are often useless. As proof of the inconsistency of the existing security system, the fact that secret security checks of the FSB conducted in 2016 showed a devastating result says that the FSB officers were able to carry shahid belts into the subway, and only 4 times were detained. Also in the Petersburg terrorist attack of 2017 there was a bomb filled with 30-40 balls for bearings, this is not so much to fix them if the shell was not metal, but from a different source the bomb shell had a fire extinguisher having a massive metal shell, based on This terrorist attack was a direct consequence of the failure of the existing system. Thus, by and large, a terrorist act can be prevented only at the level of intentions, thanks to the intelligence work of the special services, but not in the subway. The framework in this case is useless. Despite this, over the past few years, the framework has risen in price by 4 times, now the average cost is about 250,000 rub. Over the past few years, tens of billions from the budget have been spent on their purchase and maintenance. An interesting fact is that, in contrast to the 39 people who died in Russia from terrorist attacks in transport in 2012–2012, in the same period about 33,000 people died in traffic accidents on oncoming lanes, not equipped with separators, the cost of installing them on federal highways approximately equal to the amount spent on the frame. “Modern High-Tech Technologies”, whose frameworks are located in the Moscow, St. Petersburg and Nizhny Novgorod metros, have repeatedly won the tender, in situations where contests were frustrated due to the lack of access by other participants from the FSB.
