I think they really need to place greater security around these sites.. We need to preserve these camps for many generations. The reason being is that around 30% of the backwards, medieval, uneducated scum of the world purposely denies the holocaust. I say we should restores the concentration camps and take all the white supremacists and muslims and put them in those camps and spend their lives living the way the JEws were forced. We will tell them that nobody will care and call it a hoax in 60 years anyhow. Why leave the camps empty?? They are still functional and there is plenty of islamic and white nazi scum to fill them with. We will show them how effective Hitler's master plan could be when used on these holocaust deniers.
