Eric Nelson, Chauvin’s defense attorney, emphasized during his opening statement that the evidence for the case is "far greater than 9 minutes and 29 seconds."

The evidence has been collected "broadly and expansively" and includes several police experts and at least 200 civilian witnesses, Nelson said.

Nelson will spend the trial talking about "reason and common sense and how that applies to the evidence," Nelson said.

The store clerk at Cup Foods who accused Floyd of making a purchase with a fake $20 bill will be among those who testify, Nelson said.

Attorneys will also question one of Floyd’s friends who was in the Mercedes-Benz after he left the store. The friend previously stated that Floyd consumed what she believed to be two Percocet pills before police arrived. Floyd then fell asleep, Nelson said.

When officers arrived, Floyd put drugs in his mouth in an effort to conceal them from police, Nelson said.

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.

Blackwell played a portion of the 9 minute and 29 second video taken by a witness on May 25, 2020.

"For half of that time, Mr. Floyd was unconscious, breathless and pulseless," Blackwell said.

Blackwell said Floyd can be seen repeatedly heaving his right shoulder into the air. This move was an attempt by Floyd to expand his ribcage so he could breathe, as he was "pancaked" between the hard pavement beneath him and Chauvin on top of him, Blackwell said.

Chauvin watched intently as the video was played in the courtroom.

Derek Chauvin failed the responsibilities that come with the badge he was given by the Minneapolis Police Department when he pressed his knee on George Floyd’s neck and killed him, prosecutor Jerry Blackwell said in opening statements Monday.

Part of the oath Minneapolis police officers take is to enforce the law "courteously and appropriately," while “never employing unnecessary force,” Blackwell said, adding that Chauvin violated both when he engaged in the "grinding and crushing" of Floyd "until the very life was squeezed out of him."

"Mr. Chauvin betrayed his badge," Blackwell said.

Floyd was unarmed, in handcuffs and did not present a threat to anyone, Blackwell said.

"He was completely in the control of the police," Blackwell said. “He was defenseless.”

Blackwell vowed to give Chauvin a fair trial, but stated that he was "anything but innocent" on May 25, 2020 -- the day that Floyd died.

The prosecution plans to prove that Chauvin engaged in "force that he applied without the regard for its impact," Blackwell said.

During a cross-examination, defense attorney Eric Nelson walked 911 dispatcher Jena Scurry through the timeline of the encounter and pressed her on her knowledge of Minneapolis Police use of force policies.

Nelson seemed to want the jury to know that Scurry was not familiar with how police handled such incidents.

Scurry acknowledged that she has only seen police incidents play out live on monitors in the dispatch center three to four times in the seven years she has been a dispatcher.
