Yet again, it's because most elected officials are unable to toss out senior police management - and this typically includes union and fraternal order leaderships who fight hard for violent and/or racist police to continue to operate without penalty. As one more prominent example,
check out Pat Lynch's screeching about how Bill de Blasio had "blood on his hands" when a Georgia resident, having shot his ex-girlfriend in Baltimore County in Maryland, travelled to Bed-Stuy and killed two police officers. And why is this?
1) De Blasio stated that he discussed how to deal with police with his (noticably black) son - a move which police should support, given that they claim that moving too fast, moving too slow, not moving, raising one's hands, lowering one's hands, reaching for ID after they request to see ID, wearing rad clothes, wearing blue clothes, wearing a hoodie, carrying a gun in an open carry state, and being chased by a wannabe vigilante are among the many reasons that justify young black men being shot;
2) De Blasio had police stop harassing young black and Hispanic men, in keeping with federal court rulings that such behavior was unconstitutional;
3) De Blasio allowed nonviolent protests, which have long been seen as fully constitutional.
Pat Lynch also complained about the "lack of support" from city hall for this rally where police wore "I Can Breathe" shirts to mock the murder of Eric Garner for standing outside (it was claimed that he was selling loose cigarettes, but police later said that a lieutenant saw him standing around, and demanded that they remove him). Chief O'Meara, photographed in one such "I Can Breathe" shirt, was one of the cops who, earlier this year, after police spent weeks attacking protestors,
spoke at a press conference demanding that everyone "respect" them and to stop treating NYPD officers "like animals and thugs".
IOW, there's little chance that GOP officials, who are openly pro-brutality (note that De Blasio's two predecessors include then-republican Mike BLoomberg, who
applauded racial harassment by police, and republican Rudy Guiliani, who did the same -
and literally announced his mayoral bid in a rally where drunken police flung beer cans, jumped on cars, and screamed racial slurs)
I'm not surprised at all that police in Oregon have many of the same issues, if not more - Oregon initially banned black people from the state entirely, which is part of why it's a famous home area for violent racist white supremacists today. That's why I'm highly skeptical that they'll do a good job in this case.
(
I'll note that Sarah Iannorone, who is running for Portland mayor against incumbent Ted Wheeler, seems to understand the problem. What she can do about it is another matter, however)
