Wall of the Auschwitz gas chamber

The photo above, taken by Simon Robertson on January 12, 2004, shows fingernail scratches on the wall of the gas chamber in the main Auschwitz camp.  Notice the star of David on the right hand side in the middle of the photo. To the left of that star of David, there is another one in the white patch in the middle of the photo.
The following quote from Glenn Beck from the website:

The gas chambers. Glenn Beck: I have always assumed that it killed relatively quickly. But when I saw this wall – I knew I was wrong. To stand in this room where hundreds of thousands died was horrifying. The children were always on the top of the bodies. Heroes to the end. – the adults all assumed the air would be clearer higher and they tried to give these children a chance to live by holding them up close to the ceiling. It didn’t work. The gas killed everyone – but not instantly. It took twenty long horrific minutes. And the walls show it. Many of the children weren’t with their mom or dad, but with strangers. Oh, the special hell that awaited all those who were silent.
