"Dragon" at a gathering with the President. Who was liable for the participants?

In the public debate, the discussion about the Saturday gathering of president Karol Nawrocki with the community of fans, where the erstwhile kiboli gang leader Tomasz P, nicknamed Dragon, was present. State safety Service claims that "it received no guest list" and "it was the president's office at the last minute that selected the people who would be there." The NRP convinces that the gathering had "a character of an open public event".
