In the whole time of its existence, the Weimar Republic suffered from its right-wing, undemocratic personnell in its legal system. The phrase most commonly used to describe this is that its justice was "blind on the right eye".

Here are some numbers:

The failure of the Weimar Republic was to a large part owed to the fact that many of its elites were conservatives and/or political right-wingers who wanted to get rid of democratic procedures rather today than tomorrow. The new democratic forces, first of all the Social Democrats, were unable to change the personnell of the legal and beaurocratic system (exception: Prussia, where they had at least some success). The result was a right-leaning state that put away many obstacles which could have hampered the radical-right's arrogation of power.

I still can not see what this could have to do with today's terrorism, the CIA and torture...
