Kamar yadda ya bayyana, yana wakiltar rukunin da aka fi amfani da shi a Denmark, tare da wasu allurai sama da 800,000 da aka gudanar. Waɗannan allurai 800,000 suna da alaƙa da kusan 2,000 da ake zargi da faruwar munanan abubuwa, wanda ke ba da ƙimar rahoton wani abin da ake zargi mara kyau a cikin kusan allurai 400.
