At a news conference, Satterberg said the shooting was a "good faith mistake, however tragic" and no charges would be filed. But the police department's Firearms Review Board separately released findings Wednesday that describe the shooting as "unjustified and outside of policy, tactics and training." Police Chief John Diaz said Birk's resignation won't curtail a departmental investigation into his conduct. "Reaching our own administrative conclusion is a necessary step to providing a small degree of closure to the many people affected by this tragedy," Diaz said.
The killing of the 50-year-old Williams prompted an almost-immediate outcry and calls for more scrutiny of the police force. Days after the shooting, dozens marched through Seattle to protest. In December, the American Civil Liberties Union of Washington and other organizations asked the Department of Justice to conduct a civil-rights review, citing incidents including the shooting of Williams. The organizations claim some Seattle officers appear to "inflict injury out of anger" at suspects rather than to protect public safety.
On Wednesday afternoon, about 150 supporters of Williams, who was a Native American, gathered to demonstrate peacefully in lobby of City Hall, surrounding an Indian drum circle and singing. Later, several hundred people marched for hours through downtown, chanting and occasionally blocking traffic. They were escorted by police officers and no arrests were reported.
