How can a police officer, armed to the teeth, beating or shooting at an unarmed person be taken "out of context"? Did their feelings get hurt by the angry protester that they just had to fight back using physical force? What possible context are you talking about?
From what I've seen, Portland protests turns into a riots, with stones and firebombs being hurdled at police. Police then decide to clear the area (clearly within the law), antifa members refuse to move, so are forcefully moved. Usually involves antifa screaming and crying. They are then arrested and released and it starts all over again the next night.
