Well I just visited Jewish Cemetery in my hometown, Lodz. Unfortunately, there are no Jews living here today (my grandfather was a secular Jew) but before WW2 1/3 of Lodz's population was Jewish. The cemetery is considered to be the largest Jewish necropolis in Europe.It reminds me of the verse from Ecclesiastes 5:8
If you see the oppression of the poor, and the violent taking away of justice and righteousness in a district, don't marvel at the matter: for one official is eyed by a higher one; and there are officials over them.
