But things work both ways, the good and the bad. While some believe that the average Pole was complicit in the liquidation of Jews, the historian Peter Fritzsche, when asked, “Why didn’t the Poles in Warsaw help their Jewish neighbors more?,” responded that they generally did. But it took seven or eight Poles to help one Jew. It took only one Pole, acting as an informer, to turn in a dozen Jews. Even if such select anti-Semitism is contestable, we can easily imagine bad outcomes stemming from a minority of bad agents.
