The changes in the techniques of management and commandment, especially in the military, are increasingly influenced by the technical and technological progress. Electronics and robotics process (drones or unmanned aerial vehicles) cause that the decision-making process (commanding) in the army and other law enforcement institutions becomes a system in which man is only one of the elements. It is increasingly difficult to identify a person responsible for taking the entirety of the decision. Also, the technology of conducting military operations is changing. Carrying out the selective elimination of the enemy objects, including humans becomes the fashionable and the most frequently used technic in the modern military operations. Not infrequently, however, it comes to mistakes, and consequently, the civilians are being killed. Here, there are some changes in the activities of terrorists too. The process of dehumanization of decision-making process during military operations is leading to significant changes in the system of responsibility for the negative effects of operational activities. The responsibility currently is borne by the State, which, however, can be free of it when it is shown that the actions were taken because of the need to protect their citizens and worldwide security.
