When I took history in High School, we were shown films of Germans being shown video of the Nazi death camps and the enormous number of Jews killed. Piles of reading glasses. Gold melted down from teeth fillings, mountains of shoes and so on. Many Germans claimed to have no idea this was going on. Hitler was tricky. He convinced his people that these Jewish interlopers were taking German jobs and getting government help that should have gone to Germans. We know that for the ignorant, these tactics work well. So the Jews were rounded up and sent to camps in remote areas. The press wasn't allowed in. Germans who weren't "dedicated soldiers" of Hitler weren't allow in. In this way, atrocities were kept secret. And those loyal to Hitler defended him. Many, not even knowing what they were defending. Of course, some were evil and even knowing what was going on, didn't care or even approved. Camps in remote areas? Dirt walls being built up so no one outside could take pictures? Detainee's being secretly moved? Elected public officials being refused entry? Video and pictures provided by the Government? Where else have we seen such tactics?
