Polish SOP email threat author identified, not linked to school attack

Polish daily Rzeczpospolita reports that the author of an email threatening to kill PM Donald Tusk and Defense Minister Władysław Kosiniak-Kamysz was not an external attacker but someone with knowledge of the plans. The email was sent to the public address of the State Protection Service (SOP) chancellery, and authorities have established no connection to recent school attacks. The development suggests an insider or individual with specific information, raising questions about the credibility of the threat and the investigation's direction.
