Due to the upcoming visit of the US president to Poland, the Ministry of interior Affairs introduced a ban on carrying or moving weapons in an unloaded state in the area of the capital city of Warsaw. As we read in the justification, already published in the diary of Laws of the document, the ban “aims to destruct the anticipation of a situation of disturbances in the appropriate atmosphere of planned conversations, e.g. as a consequence of the failure of weapons by its owner or its removal by another persons”.
