Kapo
The moment he becomes a Kapo, he no longer sleeps with [the other prisoners]. He is held accountable for the performance of the work, that they are clean, that the beds are well-built. [...] So, he must drive his men. The moment we become dissatisfied with him, he is no longer Kapo, he's back to sleeping with his men. And he knows that he will be beaten to death by them the first night.—Heinrich Himmler, June 21, 1944
