PORTLAND, Ore. (AP) — The 2010 police killing of a Black man shot in the back after officers arrived to check on his welfare drew intense scrutiny in Portland, a grand jury rebuke, a march on City Hall and national attention from the Rev. Jesse Jackson. On Wednesday, The Oregonian/OregonLive reports Aaron M. Campbell’s death garnered international examination. Campbell’s mother, Marva Davis, and the family’s lawyer, Tom Steenson, had an hour to address an international commission examining police violence against Black people in the United States.
