The article studies modern technology solutions in armament systems concerning their use by the police, border guard and other services of social security. It presents new possibilities of surveillance conduct using sensors of various frequencies. It mainly focuses on the use of terahertz wave band in devices detecting dangerous objects.It also shows that the police can widely use infrared rays, esp. while conducting surveillance, searching for people on land and under the water, searching for drugs and explosives. Apart from thermo-detectors used at present introduction of optical detectors is suggested. First of all, it concerns photon detectors made of semiconductive materials as they are defined by a higher sensibility and response reaction than thermo-detectors. Nowadays they are developing various detectors in the shape of matrix detectors used in the thermo-imaging systems with mechanic scanning as well as electronic scanning which is applied in the production of observation devices with digital correction of thermo-vision.One of the new technologies employed by the police is acoustic sensors that can be used to detect and identify objects, define the type of weapons and missiles, recognize the speech and identify speakers. Scientists analyze and develop different acoustic techniques, mainly sensory techniques which use volumetric and surface sound waves propagating in diverse environments. Acoustic sensors are indispensable in optical and radio detection of parameter changes in opaque environment.Besides, the author pays attention to possibilities to use of lasers to detect dangerous substances at far distances. He also analyses the increasing importance of “non-lethal weapons” in the police and other services, e.g. use of acoustic and electromagnetic devices.

One of the processes characterising the changes in the modern world is the intense urbanisation of public space. Generally speaking, this is manifested through an increase in the urban population rate in a given area. From the point of view of the security of large urban centres, the most important issue is the growing concentration of population in the current area. However it is equally important to ensure security in the context of its spatial development, i.e. in an ever-expanding zone that creates an agglomeration. When seen like this, urbanisation is associated with significant challenges for the institutions responsible for security both in quantitative and qualitative terms. Modifications of security systems for large urban areas forming the agglomerations should take into account all of the following: demographic, economic, and socio-cultural factors, and, finally, the changes in the lifestyle of the inhabitants of these agglomerations. While searching for directions of institutional and functional changes for security systems, it seems important to characterise contemporary agglomerations, and to identify common features and define the most serious threats. These common features are primarily high population density and infrastructure concentration, including critical infrastructure systems. The threats resulting from this are primarily threats to public order and security, as well as terrorist threats, and, in the area of technical functioning of the agglomeration, a widespread power failure, a so-called ‘blackout’, resulting in an avalanche of secondary hazards. These threats seem to be a direct consequence of the metropolitan nature of the region where they occur.

The paper presents the complexity of issues related to the security of mass events based on social research and statisticaldata obtained from the Police about protected football matches in Poland during the period from 2010 to 2014. The issueof the security of this type of event is considered knowing that the delinquency of football hooligans is not limited to stadiumsbut also occurs in the areas adjacent to the sports facilities. Over the years, there has been no accepted, unambiguous definitionof stadium crime which, by implication, confirms that there are significant challenges facing scientists dealing with the phenomenonof the subculture of football hooligans. In the paper, in search of effective methods to prevent stadium crime, the role of the policemansupporter, the so-called “spotter”, is described. According to the authors, it was a good idea to introduce a police officer into the fans’environment. It must be remembered that in practice, due to the fact that stadium crime is the domain of crime groups operatingwithin a specific subculture, the explicit penetration of these environments is a very difficult process. Hence the institution of spottercan fulfil its task by educating children and young people, who are impervious to the influences of hooligan structures.

In the era of common access to freedom on the Internet, there are more and more controversies between advocates of complete freedom and followers of the idea of limiting the usage of the global network’s resources. Should the Internet become a space of unlimited freedom? Contrary to common belief, the answer to such a question is not that obvious, although intuitively one would like to say yes. The Internet is basically an egalitarian tool of communication, a space of easy creation and transfer of content, for which the only limit is technology and unlimited human imagination. Freedom seems to be not only an immanent, but even a constitutive feature of the virtual space in which the Internet functions.
