Due to the upcoming visit of the president of the United States to Poland, the Ministry of Interior introduced a ban on carrying or transporting weapons in the state unloaded in the area of the capital city of Warsaw. As we read in the explanatory memorandum, already published in the diary of the Act of a document, the ban "is intended to destruct the anticipation of a situation affecting the appropriate atmosphere of planned talks, e.g. as a consequence of the failure of a weapon by its owner or its removal by another persons".
