Dutch municipalities had comprehensive files on every citizen, including religion. Germany invaded, Holland capitulated in 5 days, and the files proved an organizational treasure trove for rounding up jewish families and deporting them. "Also, the civil administration was advanced and offered the Nazi-German a full insight in not only the numbers of Jews, but also where they exactly lived." - https://en.wikipedia.org/wiki/History_of_the_Jews_in_the_Netherlands#The_Holocaust https://en.wikipedia.org/wiki/History_of_the_Jews_in_the_Net... It wasn't immediately obvious what, exactly, was happening to the Jewish families when Germany took over. But even if it had been, destroying all those files in 5 days would have required extraordinary coordination and determination. And that is assuming you make the decision to scorch the earth the second Germany attacks; not exactly a move which would inspire confidence. Underground resistance forces spent the following five years trying to burn down as many town halls as they could.
