A group of Tulsa activists held a press conference Tuesday and said the conviction of former Minneapolis police officer Derek Chauvin is an important step but believe there’s still work to be done.

Chauvin was found guilty Tuesday on all three counts: second-degree murder, third-degree murder and second-degree manslaughter.

“We have to be sure to push the needle towards policy change,” activist Dr. Tiffany Crutcher said. “That’s the only way we’ll hold police officers accountable in this country.”

Leaders from the historic Greenwood District said they believe permanent change is necessary to achieve racial justice.

“We got a guilty verdict today, but George Floyd is not coming back,” community organizer Greg Robinson said. “So, when we think about what is needed, we have to understand that preventing these atrocities is what is needed.”

Speakers included Dr. Crutcher of the Terence Crutcher Foundation; Greg Robinson, former Tulsa mayoral candidate and part of MET Cares; and Nehemiah Frank, editor-in-chief of the Black Wall Street Times.

Tulsa Mayor G.T. Bynum also addressed the verdict Tuesday on his Facebook page, saying in part that the verdict is a reminder that "accountability will be rendered."

"I have yet to talk with a police officer who wasn’t disgusted by Derek Chauvin’s conduct in the video depicting the murder of George Floyd.

I also know that good police officers - those who uphold the highest standards for their profession in an incredibly difficult time - want bad police officers held accountable. Today’s verdict is a reminder that our justice system works, and that accountability will be rendered for those who betray that sacred trust between guardians and the citizens they protect."
