Two Portland residents say they will appear before a federal grand jury in Seattle Thursday in an investigation of anarchist activity, according to a statement they released on [August 1]. Grand jury subpoenas have also been served to activists in Olympia and Seattle ... according to the Seattle Chapter of the National Lawyers Guild, which identifies itself as an association of progressive lawyers. The guild urged the U.S. Attorney's Office to drop the subpoenas [because] they were being used "as a pretext for harassing political activists." "It concerns us any time there are law-enforcement raids that target political literature, first amendment-protected materials," [guild spokesman Neil] Fox said. Two weeks before a heavily armed, July 25 FBI raid that Dennison Williams and Leah-Lynn Plante said took place at their Portland home, the Seattle Police Department SWAT team seized evidence connected to the May Day investigation from a Judkins Park apartment of Occupy Seattle members. In both cases, those searched told media that law-enforcement charged into their homes [with a battering-ram] early in the morning and used a stun grenade, a non-lethal object that creates a disorienting loud bang and bright light. Williams told The Oregonian that the FBI took his laptop computer, cell phone, two thumb drives, multiple pieces of black clothing, and a T-shirt that read on the front "Multi Death Corporations."
