Before the King march kicked off last week, three parade workers found the gray backpack on a bench at the northeast corner of North Washington Street and West Main Avenue in downtown Spokane.  No threat was made before the device was found, and no note was found with the backpack, authorities said.  The FBI said last week it will consider regional neo-Nazi activity in its investigation of the backpack bomb.  Two T-shirts were found in the Swiss Army-brand backpack, authorities said. One shirt says "Treasure Island 2009" and the other reads "Stevens County Relay For Life June 25th-26th 2010."  Frank Harrill, special agent in charge of the FBI's Spokane field office, said last week that authorities know of no link to "any specific group or individuals" and called reports linking the bomb to recent neo-Nazi activity in a nearby Idaho town "premature."  The bureau is looking into the incident as "an act of domestic terrorism," and investigators are analyzing "every square millimeter" of the backpack, Harrill said.  Tony Stewart, one of the founders of the Kootenai County Task Force on Human Relations in nearby Coeur d'Alene, Idaho, told CNN last week that he found the timing of the planted bomb and two recent neo-Nazi activities in Coeur d'Alene "just too overwhelming" and suggested hatred was also behind the Spokane bomb. Coeur d'Alene is 35 miles east of Spokane.  But Stewart had no evidence tying the Spokane bomb to the two activities in Coeur d' Alene. Earlier this month, a handful of neo-Nazis protested two Mexican restaurants with signs saying, "This is white land" and "We want you out of here," he said.  Then, during the evening of the King holiday, about 15 neo-Nazis demonstrated outside the Human Rights Education Institute in downtown Coeur d'Alene, Stewart said.  About the Spokane bomb discovery, Stewart said: "It's clear that it was an attempt to end the march and attack human rights advocates.
