Additional Information This was part of a multiple attack 197004190001, 197004190003, and 197004190004. Although leftists, rightists, Blacks, and Whites have been accused of being perpetrators of the bombings, the general consensus is that the attack was carried out by White Racists. This attack had a great psychological affect on the city of Seattle. The mayor enforced the notion that the citizens of the Emerald City were "frightened" and needed answers. There was an attempted bombing against the same realty office a month later (197005150004).
