The family of Terence Crutcher claimed a \u0022small victory\u0022 late Thursday after the Tulsa County district attorney charged police officer Betty Shelby with manslaughter in the first degree for killing the unarmed father of four.\u0022While we are pleased to learn that the officer who senselessly killed by my beloved twin brother will face criminal charges for her senseless act, we understand that nothing will bring him back,\u0022 said Terence\u0026#039;s sister, Dr. Tiffany Crutcher, during a press conference following the announcement.But, she cautioned, \u0022we know the history of these cases,\u0022 referring to the countless other incidents where police officers were let off after killing a black civilian. \u0022We know she gets charged but we get no convictions.\u0022Crutcher said the family would be \u0022vigilant\u0022 in following this case, and called for \u0022transparency and accountability.\u0022\u0022The chain breaks here,\u0022 Crutcher vowed. \u0022We are gonna break the chains of injustice, the chains of police brutality. The chain breaks here right in Tulsa, Oklahoma. I\u0026#039;m challenging everyone from all walks of life to join with us as we move forward.\u0022This is a \u0022small victory...but we know we got to get ready to fight this war. Join arms, lock arms with us as we go out and make everyone aware that today we can change this nation.\u0022Ryan Kiesel, executive director of the American Civil Liberties Union (ACLU) of Oklahoma, echoed those remarks. In a press statement, he called the charges \u0022welcome and appropriate,\u0022 but said the group continues to \u0022remain concerned for Tulsa\u0026#039;s communities of color and for Black Americans across this nation.\u0022\u0022The officers who callously failed to render immediate aid when Terence was shot and bleeding to death and the officer in the helicopter who referred to Terence Crutcher as \u0026#039;one bad dude\u0026#039; are evidence of a dehumanizing culture we see all too often,\u0022 Kiesel said.\u0022As we continue to grapple with an epidemic of police brutality and killings that disproportionately affect people of color, we must not assume the conversation and the move towards desperately needed criminal justice and policing reforms ends today,\u0022 he concluded.
