Activists have begun a rally and plan to march Monday afternoon to call for Portland State University to disarm campus officers after a fatal police shooting this summer.

The demonstration — held by the Portland State University Student Union, which has long pressed the university to disarm its police — began at noon on the first day of the fall term. It comes months after the killing of Jason Washington, 45, outside the Cheerful Tortoise bar near campus and in the days after authorities released records and videos of the incident.

Speakers, amid "Disarm PSU" chants from a crowd of a couple hundred, are calling for campus administrators to remove guns from the university's police force. They also seek a memorial to Washington and for the officers who shot him to be fired.

Shortly before 1 p.m., the speeches ended and demonstrators marched to where Washington was shot. His widow, Michelle Washington, flanked by Washington's three daughters, addressed the crowd.

"His motto was God, family, friends and country," Michelle Washington said. "He was our everything. He was needlessly and violently taken from us."

Washington's brother, Andre Washington, is attended the rally.

The march continued through the urban campus along city streets to the Academic and Student Recreation Center, where the university's board of trustees meets.

After more speeches, demonstrators moved to the Campus Public Safety office at Broadway and Montgomery Street. Leaders announced intentions to occupy the area in front of the building.

"This is where we're putting our foot down," said activist Alyssa Pagan, amid chants of "Occupy PSU."

"Please stay as long as you can," Pagan said to the crowd, which responded with a chant of "We're not leaving."

A group of about 15 demonstrators then sat down in front of the office and said they will be there "indefinitely." Some brought camping gear and began setting up a tent. Shortly after 2 p.m., the rally ended and some of the crowd began dispersing.

The university released a statement about 1:30 p.m.:

Jason Washington's death has had a profound impact on the Portland State community, and the university recognizes the right to participate in peaceful protest. PSU has hired an independent security consulting firm to review campus safety policies and procedures, which will hold a series of public forums in the upcoming weeks on this issue to provide students, faculty, staff and the public opportunities to speak. That review will study all options to protect the campus and make recommendations to President Rahmat Shoureshi and the PSU Board of Trustees. The PSU student government president and campus administrators will also send a message tomorrow to PSU students about the resources available for those searching for support or seeking opportunities to reflect on the topic.

The June 29 encounter marked the first fatal shooting by the university's police force, which began carrying guns three years ago in a decision decried by activists and some students.

A Multnomah County grand jury ruled in mid-September that two officers were legally justified in killing Washington, a black man who was a Navy veteran and U.S. postal worker.

He was shot nine times, according to a report released last week by the Multnomah County Medical Examiner's office. Officers Shawn McKenzie and James Dewey fired 17 shots at Washington.

Washington was holding a friend's handgun amid a street fight outside the campus-area bar when officers ordered him to drop it, then opened fire.

PSU has released body cam video of both officers, which shows them arriving at the scene amid a drunken melee. The video captures the chaotic seconds that unfold before and after Washington's death.

Police at the school first began carrying guns on July 1, 2015, after a 2014 Board of Trustees vote in favor of deploying some officers with guns.

The vote was a controversial one among the campus community, especially for the student group Disarm PSU.

Portland State University President Rahmat Shoureshi has said in a statement that Washington's death "has deeply shaken all those involved as well as the greater campus community."

"We are determined to learn from it," the statement said.

In a separate statement, the university's Board of Trustees has said it was prepared to revisit the policy of arming campus cops "with open minds — to determine whether the current policy should be continued or changed."
