Demands for accountability and sweeping reforms mounted Saturday after Atlanta police shot and killed Rayshard Brooks, a 27-year-old black man, Friday night amid a wave of global protests against police violence and systemic racism sparked by the death of George Floyd in Minneapolis late last month.\u0022Sleeping in a drive-thru must not end in death.\u0022—Stacey Abrams, Georgia activistIn a message to Atlanta Mayor Keisha Lance Bottoms on Saturday, the Georgia NAACP tweeted that the city\u0026#039;s police department \u0022needs a serious overhaul. The continuation of these kinds of actions require immediate resolution. Instead of seeing an improvement, it continues to happen day after day.\u0022The Georgia NAACP said the Atlanta Police Department (APD) \u0022has had a culture of excessive use of force\u0022 and called for Police Chief Erika Shields to be \u0022relieved immediately.\u0022 The group also demanded the release of \u0022body cam footage and all surveillance video from surrounding buildings\u0022 to shed light on Brooks\u0026#039; killing.Bottoms announced during a Saturday afternoon news conference that Shields offered her resignation, which she accepted. The mayor also said that she does \u0022not believe this was a justified use of deadly force\u0022 and she has \u0022called for the immediate termination of the officer\u0022 who shot Brooks.\u0026nbsp;If local leadership won’t hold those accountable, then #WeThePeople will. https://t.co/bVJlvgPVLC— Georgia NAACP (@Georgia_NAACP) June 13, 2020Brooks died following surgery at a local hospital after APD officers were dispatched to a Wendy\u0026#039;s restaurant around 10:30 pm Friday to respond to \u0022a complaint of [Brooks] in a vehicle parked in the drive-thru asleep, causing other customers to drive around the vehicle,\u0022 according to the Georgia Bureau of Investigation (GBI), which is investigating the shooting. The involved officers have not yet been publicly identified.GBI initially said that after Brooks failed a field sobriety test, \u0022officers attempted to place the male subject into custody. During the arrest, the male subject resisted and a struggle ensued\u0022 involving a Taser. In an updated statement Saturday, GBI said, \u0022An earlier account of this incident was based on the officer\u0026#039;s body cam which was knocked off during the physical struggle, preventing the capture of the entire shooting incident.\u0022Video footage of Brooks\u0026#039; encounter with APD circulated on social media and appears to show him running away from officers when he was shot. The updated GBI statement said the bureau had \u0022obtained additional surveillance video from the Wendy\u0026#039;s restaurant,\u0022 which was released to the public.The GBI is releasing surveillance video showing the exchange between Atlanta Police Officers and Rayshard Brooks from Wendy’s restaurant - Atlanta OIS 6.12.20 https://t.co/dNlBDpXsRp— GA Bureau of Investigation (@GBI_GA) June 13, 2020\u0022Agents have also reviewed video posted on social media,\u0022 GBI added. \u0022These new videos indicate that during a physical struggle with officers, Brooks obtained one of the officer\u0026#039;s Tasers and began to flee from the scene. Officers pursued Brooks on foot and during the chase, Brooks turned and pointed the Taser at the officer. \u0026nbsp;The officer fired his weapon, striking Brooks.\u0022Rev. James Woodall, state president of the Georgia NAACP, told reporters Saturday that \u0022this is not the first time a black man has been killed for sleeping.\u0022 He added that \u0022while Atlanta is often called \u0026#039;the Black Mecca,\u0026#039; the Atlanta Police Department has a continued history of antagonizing our communities.\u0022The Washington Post reported that during a call with journalists Saturday afternoon,Woodall stopped short of calling for Bottoms\u0026#039; resignation, but said that it was her responsibility to ensure citizens have \u0022the kind of police department the City of Atlanta deserves.\u0022 Woodall also called out the lack of public statements from the mayor\u0026#039;s office and police department as of early Saturday afternoon.Woodall said the Georgia NAACP has hired a private investigator and that a press conference would take place Tuesday morning.According to the Atlanta Journal-Constitution, Woodall was asked if his group has been in contact with Bottoms or APD. \u0022At this present moment,\u0022 he said, \u0022we have not heard from the mayor herself or the police chief, and the silence is deafening.\u0022Stacey Abrams, a Georgia voting rights activist who ran for governor as a Democrat in 2018, took to Twitter Saturday to demand investigations and accountability in this case as well as broader reforms in local policing. She declared: \u0022Sleeping in a drive-thru must not end in death.\u0022The killing of #RayshardBrooks in Atlanta last night demands we severely restrict the use of deadly force. Yes, investigations must be called for - but so too should accountability. Sleeping in a drive-thru must not end in death. https://t.co/LKsiwA48Ll— Stacey Abrams (@staceyabrams) June 13, 2020Brooks\u0026#039; death added to the growing outrage over police violence toward people of color, particularly black Americans, that has fueled #DefundPolice demands and demonstrations across the U.S. and in other countries for nearly three weeks.https://t.co/PWu8PsAWRF https://t.co/o3HVPfqKlI— Scott Trubey (@FitzTrubey) June 13, 2020Saturday also saw demonstrations in other U.S. cities including Washington, D.C. as well as in London, Paris, Prauge, and Perth, the capital of Western Australia.
