This is a hand hold some people's heads. It means Nazi is tight catch up these victims lives. Almost heads open their their eyes to express their afraid about dead and the afflictions from Nazi. Some people lowered their eyes,because they are sad about subsequent life. They give up resistance. It describes a appearance about power and weak.
We are human, why those civilians can do so cruel things and think they knew nothing. I can not believe what happened during the time of Holocaust.
