Shapiro says that the sheer number of camps may end one of the lingering protestations surrounding the Holocaust -- that ordinary people knew nothing of the killing underway in their locales. "In most towns, there was some sort of prison, or holding area or place where people were victimized," Shapiro says. "Think about what this means. For anyone who thinks this took place out of sight of the average person, this shatters that mythology. There was one Auschwitz. There was one Treblinka. But there were 20,000 other camps spread through the rest of Europe."
