The universities refused to admit Jewish students, denied degrees to those already enrolled, and dismissed Jewish faculty. Government transportation bureaus handled the building arrangements with the railroads for the trains that carried Jews to their death. And so the point that's being made here is this could not be done just with Hitler and some of his close associates. To kill millions of people on this scale, you needed an entire apparatus. And hundreds of thousands, if not millions of people, were involved in some way. And at least several hundreds of thousands of people within Germany must have been aware of what was happening. Needless to say, the death toll was considerable.
