So throughout all of these cases, German troops were stationed there so of course there were amenities, like pools, to keep the soldiers occupied. Obviously the prisoners there would not have access to these things and someone has to be deliberately stupid to not realize this.

btw I've been on tour at Auschwitz and one of the first things that they show off is the "pool for jews" lol
