In the 2000s, the DKU became associated with violent demonstrations in Denmark.[7] During the Ungdomshuset riots in 2007, the organization's president, Cathrine Frederikke Pedersen, advocated the use of firearms as a legitimate means for achieving political goals.[8] Pedersen said that except for WMDs, all violent actions were permitted.[2] The Danish Security Intelligence Service expressed concern about the DKU's radicalization.[8]
