I mean Hitler made a similar speech announcing the night of the long knives.

If anyone reproaches me and asks why I did not resort to the regular courts of justice, then all I can say is this. In this hour I was responsible for the fate of the German people, and thereby I became the supreme judge of the German people. I gave the order to shoot the ringleaders in this treason, and I further gave the order to cauterise down to the raw flesh the ulcers of this poisoning of the wells in our domestic life. Let the nation know that its existence – which depends on its internal order and security – cannot be threatened with impunity by anyone! And let it be known for all time to come that if anyone raises his hand to strike the State, then certain death is his lot.
