Verordnung des Reichspräsidenten zum Schutz von Volk und Staat
The Nazis took advantage of the fire to advance their own political aims. The Reichstag Fire Decree, passed the next day on Hitler's urging, suspended basic rights and allowed detention without trial. Activities of the German Communist Party were suppressed, and some 4,000 Party members were arrested. Göring demanded that the detainees should be shot, but Rudolf Diels, head of the Prussian political police, ignored the order. Some researchers, including William L. Shirer and Alan Bullock, are of the opinion that the Nazi Party itself was responsible for starting the fire.
