On April 1, armed SA men took up positions in front of Jewish businesses and tried to prevent customers from spending money in them. Some troops painted anti-Semitic slogans and Stars of David on display windows; others were content to hold up signs calling for a boycott and to curse at Jewish businessmen. Some areas also saw looting and acts of violence.All in all, this display of activism made a very negative impression on most people, and the thuggish SA men with their uneducated bellowing were left even less popular among the general population than they had been before. Although very few Germans openly declared their solidarity with their Jewish fellow citizens, the boycott did not, as it was intended to do, set German gentiles against German Jews. On the contrary, ordinary people felt sorry for them, and if reports by the Nazis, who were disappointed by the boycott, are to be believed, the amount of commerce done afterward by Jewish-owned business did not decline at all.
