Cole Tomas Allen, who fired a gunshot at a security officer during the White House Correspondents' Dinner held at the Washington Hilton hotel, had previously sent a manifesto to his family expressing his disdain for hotel security. In the manifesto, he described himself as the 'Friendly Federal Assassin' and criticized the security's arrogance, noting that he entered the hotel with multiple weapons without being checked. He indicated that he intended to target officials from the Donald Trump administration, specifically mentioning the former president as his main target. Allen chillingly stated his choice to use 'buckshot' instead of slugs to reduce casualties, while still being prepared to harm attendees at the event. Fortunately, he was subdued before he could inflict more damage. The incident raised serious concerns about security measures at the event, which had over 2,300 guests and involved multiple security checks, including magnetometers operated by the Secret Service.
