The civil rights attorneys representing the family of George Floyd -- Benjamin Crump, Antonio Romanucci and L. Chris Stewart as well as the Rev. Al Sharpton -- spoke to reporters Monday morning.

“Today starts a landmark trial that will be a referendum on how far America has come in its quest for equality and justice for all,” Crump said, with Floyd’s family present.

Crump stressed that the evidence against Chauvin speaks for itself, saying this “murder case is not hard."

“We're not asking for anything extraordinary,” Crump said. “We're asking for equal justice under the law.”

Hennepin County District Court Judge Peter Cahill will excuse the 15th juror chosen for Chauvin's trial as court gets underway.

The first 14 jurors are present and will be sworn in and seated.

Eight jurors are white and six are people of color, including four jurors who self-identify as Black. There are nine women and five men.

Three people who witnessed Chauvin kneeling on Floyd’s neck called 911 on the officers who were at the scene, Blackwell said.

A first responder, who was distressed that the officers were not checking Floyd’s pulse or performing chest compressions on him, called the police, Blackwell said.

Another man, who Blackwell described as a "very focal” bystander with a background in security and mixed martial arts, also called the police.

The third person was a 911 dispatcher who could see the encounter through a fixed police camera on the scene.

The incident was "so unusual, and for her, so disturbing," that she called a sergeant at the police department to alert him to what was happening, Blackwell said.
