Police driving their SUV cruisers into protesters in Brooklyn, New York.National Guard and local officers firing paint gun rounds at people standing on their own front porch in Minneapolis, Minnesota.Massive armored S.W.A.T. vehicles and lines of riot police in Columbia, South Carolina and elsewhere.Police units firing rubber bullets and tear gas at kneeling, non-violent demonstrators in Dallas, Texas.Riot police knocking an elderly man walking with cane to the ground in Salt Lake City, Utah.These were just some of the outrageous and violent scenes captured on video Saturday night amid demonstrations and uprisings in cities across the U.S. in protest of the killing of George Floyd in Minneapolis last week and the long history of police violence and social neglect in the country.This is the first accurate headline I’ve read tonight. https://t.co/sbjvxcGZzE— Ayelet Waldman (@ayeletw) May 31, 2020Here\u0026#039;s what happened in Brooklyn:Shocking scenes of two police cars in Brooklyn just driving through a crowd of protesters. pic.twitter.com/ZuZjhOHoNY— redfish (@redfishstream) May 31, 2020This is what it looked liked when people standing on their front porch in a quiet neighborhood in Minneapolis when the National Guard marched down the street telling everyone to \u0022Get in you house, now!\u0022 before ordering \u0022Light up em\u0022 and opening fire with paint pellets:Share widely: National guard and MPD sweeping our residential street.

We call for an immediate end to any excessive use of force and for law enforcement to ensure and protect the legal right to protest.\u0022Ward said that all \u0022unnecessary or excessive force must cease immediately, and all instances of potentially excessive or unnecessary force against protesters must be investigated and any officers who broke the law must be held accountable.\u0022 Ward argued that it is equipping police officers with military gear and asking them to behave as soldiers in the first place is what often leads to more violent clashes.\u0022Police must engage in de-escalation, before the situation worsens,\u0022 she said. \u0022They should de-militarize their approach and engage in dialogue with protest organizers to reduce tensions to prevent violence or to stop it quickly as soon as it breaks out in order to protect the right to peaceful assembly.\u0022Amnesty also singled out President Donald Trump by name for sowing further division and violence:\u0022President Trump must end his violent and discriminatory rhetoric and policies.The U.S. government at all levels must ensure the right to protest as guaranteed by international law.”— Amnesty International USA (@amnestyusa) May 31, 2020In a widely shared commentary on Friday night, philosopher and social justice activist Dr. Cornel West argued that what is being witnessed right now in the U.S. is a \u0022perfect storm\u0022 of discontent that blends the fresh outrage of Floyd\u0026#039;s killing—and the similar killings of others by police—with the underlying injustice of an American capitalist system that cannot fulfil the human needs of its people and that is soaked in racism and inequality.\u0022When you talk about the masses of black people—the precious poor and working-class black people, brown, red, yellow, whatever color—they\u0026#039;re the ones left out and they feel so thoroughly powerless, helpless, hopeless—then you get rebellion,\u0022 West said.Worth repeating that all of the police violence you see happening right now has been happening for a long time before there were any camera phones to record it. It’s a daily phenomenon in communities across the country. It’s structurally embedded into how these forces operate.— Clint Smith (@ClintSmithIII) May 31, 2020Rep. Alexandria Ocasio-Cortez in a viral video post on Saturday afternoon said that anyone calling an end to the so-called \u0022unrest\u0022 sweeping the nation in the wake of Floyd\u0026#039;s death is being nothing but hyppocritical and empty if they are not pairing that demand with calls to reform that systems that fuel such anger and despair.\u0022If you\u0026#039;re trying to call for the end to unrest, but you don\u0026#039;t believe healthcare is a human right,\u0022 said Ocasio-Cortez. \u0022If you\u0026#039;re afraid to say Black Lives Matter. If you\u0026#039;re too scared to call out police brutality—then you aren\u0026#039;t asking for an to unrest. You are asking for injustice to continue and for your people to continue to endure the violence of poverty, the violence of lack of housing access, the violence of police brutality and not say a damn thing. That\u0026#039;s what you\u0026#039;re asking for.\u0022In response to the specific of police violence displayed Saturday in Brooklyn when the police vehicles tried to mow down protesters, Ocasio-Cortez rejected the argument put forth by New York City Mayor Bill DeBlasio and others that such use of force was justified.\u0022NO ONE gets to slam an SUV through a crowd of human beings,\u0022 she tweeted. \u0022Running SUVs in crowds of people should never, ever be normalized. No matter who does it, no matter why.\u0022Update: This post was updated to include comment from Amnesty International.
