In Phoenix on Tuesday evening, a white police officer who was feeling threatened used lethal force on an unarmed black man named Rumain Brisbon. The incident left the officer unharmed and Brisbon, 34, dead with two bullet wounds in his torso at a north Phoenix apartment complex.

Brandon Dickerson, who told FOX-10 that he was with Brisbon when the officer approached and that he didn’t hear the officer give any commands. According to police, Brisbon ran when approached; the Phoenix Police Department claims that after a brief struggle, Brisbon reached for a bottle of prescription painkillers in his pocket—which the officer mistook for a gun.

Phoenix police quickly released a detailed account of the killing for the media on Wednesday morning in what officials said was an effort to promote transparency, especially in light of the unrest that has played out in Ferguson and New York City following the deaths of unarmed Black men at the hands of White officers. But portions of that account have already been challenged by some witnesses and community activists who say that the officer’s use of force was excessive and that Brisbon’s death was unwarranted.

How long are we as a nation going to pretend that we do not have a problem with systematic white supremacy,and this problem is allowing the legalized lynchings of black people on a daily basis at this point?
