"Portland protesters drew a line in the sand warning onlookers and press not to shoot footage in an “autonomous zone”, set up to reclaim a house where a black family was evicted, as they returned for a third day Thursday. Activists behind the armed occupation of the “Red House on Mississippi” urged camera-wielding lookie-loos not to enter the sealed-off streets surrounding the Kinney family home in a heated warning on Twitter.
“The space at the Red House is an active eviction blockade. If you enter that space not to defend the Kinney family, but to livestream or film the risks that others are taking for your personal gain, then you are a guest. If you aren’t respectful, you will be an unwelcome one,” the PNW Youth Liberation Front, a group of social justice activists, tweeted Thursday morning."
