Editorial Dear readers. We have included four articles in the last 2021 issue of the Journal of Criminal Justice and Security. The articles are very diverse in their content, but they address important content in criminal justice and security studies. The authors address issues of fairness and efficiency in the prosecution of terrorist fighters, the competence of police officers in dealing with aggressive psychiatric patients, the use of advanced technology in private security activities and the importance of competitive intelligence to ensure the efficiency of contemporary businesses. The contents thus range from public policing to private security and corporate security. In the paper Criminal Liability and Prosecution of Islamic State Fighters in Iraq, Anica Ferlin summarises the operation of the Islamic State in Iraq and includes a review of law enforcement by the authorities. This paper aims to add to the body of expertise by presenting the measures taken by the authorities to prosecute fighters of this terrorist organisation. The results show that the Islamic State did commit war crimes, crimes against humanity and crime of genocide in Iraq. However, no individual has been held accountable for these crimes at the international level and to date. The paper identifies some shortcomings related to the prosecution of the Islamic State in Iraq. The author indicates the direction of further necessary practical measures that should be taken to guarantee effective and fair prosecution of Islamic State fighters and the limitation of the risk of further radicalisation. In the paper Police Instruments of Restraint Against Persons with Health Problems - Analysis of the Use of Expert Grips and Holds as Forms of Physical Force Branko Gabrovec, Tilen Zupan, Srecko Felix Krope, and Branko Lobnikar aim is to determine the capability of police officers to control violent patients with health problems and analyse the competencies of police officers in controlling violent persons. The specific nature of the situation dictates the need for additional skills and training for the successful implementation of police procedures that do not jeopardise the subsequent treatment procedures with the patient. The authors' analysis has shown the lack of knowledge and skills of police officers in dealing with violent persons who have health issues or are under the influence of drugs or medications, and in addition to that, the police officers are not afforded appropriate training in this field. Miha Dvojmoc, Patricija Luneznik and Kaja Prislan in the paper Adoption of Advanced Technological Solutions in Slovenian Private Security Companies, analyse the use of advanced technological solutions in the private security industry. Its primary purpose is to upgrade security services and resolve private security companies' human resource issues. Based on the interviews, the authors concluded that introducing digitalisation into the private security industry could appropriately address the shortage of human resources while also expanding 353 the products provided by security services. The authors also emphasise that the findings could have implications for both public and private policing. The last paper in the current issue of the Journal of Criminal Justice and Security is written by Žiga Prime. Using the systematic review of the literature, the author thoroughly analyses The Use of Tools for Obtaining Data from Publicly Accessible Sources for the Purpose of Competitive Intelligence in Enterprises. Over the past decade, obtaining data from publicly accessible sources has developed extremely rapidly, and more effective tools are being developed to automate processes. Existing studies highlight the importance of competitive intelligence activities in companies utilising obtaining data from publicly accessible sources for better decision-making. The author identifies a lack of trained personnel and adequate software systems for optimal business use. The editorial board hope the readers will find the articles worth reading and a good source of fresh ideas for future research and hopefully new papers.
