The decision to place Spokane police Assistant Chief Scott Stephens on paid administrative leave more than two months ago was based on erroneous assertions that he’d become so upset over his demotion that he was threatening workplace violence, an attorney said Tuesday. Stephens’ attorney, Bob Dunn, of Spokane, said the assertions are false but that Chief Frank Straub and Mayor David Condon are using the allegation to ruin the veteran officer’s reputation in an attempt to force him out of the department. The alleged threats were relayed to city officials by a member of the police department who claimed the assistant chief told her that he “was going home to get his weapon,” Dunn said.
