The world globalisation processes have inevitably been accompanied by the development of new forms of crime and the occurrence of crisis incidents (acts of terrorism, major transportation accidents, construction accidents, or natural disasters). The above phenomena increase the demand for knowledge, the use of which may directly or indirectly influence the effectiveness of agencies responsible for internal security. With its basic goal of spreading the knowledge of the protection of public safety and order, the scientific journal Internal Security is one of the many ventures aimed at meeting the demand. The journal is oriented towards security aspects of universal scope. It is a forum where views and opinions are exchanged by specialists of various branches (both scientists and practitioners) from different countries, and in particular European ones. Entrepreneurs of non-public sector are welcome to exchange their opinions in the journal, as well. In many cases methods and mechanisms which are used to ensure safety are of universal nature and they can be applied by both, public and non-public sectors.Tomasz Safjański The Integrated Fight Against Organised Crime in the Baltic Sea Region(BALTCOM) — Genesis, the Main Fields of Activity and Prospects for Development 7 Mihály Fogarasi, István Kovács How to Reveal the Constructed Worlds: the 2006’s Riots in Budapest 19 Aleksander Babiński, Paweł Lubiewski, Daniel Kołnierowicz Ways of Increasing the Level of Safety and Security at Locations Proposed for World Youth Day 2016 41 Adrian Szumski Instruments Used by Interpol in the Fight against International Trafficking in Human Beings 59 Waldemar Kawka Illegal Use of Explosives — an Incidental Phenomenon or the Seeds of the Next Real Threat to Collective Security and Public Order? 69 Mojmír Mamojka, Jacek Dworzecki Development of Commercial Law in the Slovak Republic — Outline of Problems 81 Bernard Wiśniewski Public Security in the Polish Law on State of Emergency 91 Lucia Kurilovská, Marek Kordík Protection of Creditors and the Imposition of Sanctions Against Assets and Property in the Slovak Republic 101 Ihor Rohatiuk Basic Principles of the Prosecutor in Criminal Proceedings Under Criminal Procedure Code of Ukraine 111 Paweł Suchanek Deactivation of Weapons from the Perspective of the European Union and Kosovo 123 Izabela Jankowska-Prochot The Use of a Document Attesting an Untruth.
