the balance of the text declares "emergency state" declarations are all "basically legal" -- a highly dubious legal proposition. "Law" is the tool of every tyrant because mere law is nothing less than force itself. Compliance with Justice, Inalienable rights and proper interpretations of duly people-enacted constitutional provisions as well as their underlying principles are all necessary to rescue law and make it Justice. In the meantime, law may and always does parade around as Justice itself, though it is not.
The portions of the post that deal with historical German coalition facts are unobjectionable, though I can't verify them as facts, I assume they are. The legal conclusions implying that a ruler in a free society can declare an "emergency State" as Hitler did and make themselves Dictator are pure baloney -- unless a very narrow defition of "legal" is used in which case it misleads the reader into thinking Hitler's totalitarian powers were Just in any meaningful sense.
Again, dictators and tyrants ALWAYS cloak their abuses in law, so one has to be careful with using the term "legal" in this and related contexts.
