Chauvin watches intently as prosecutor plays witness video
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.

"Mr. Chauvin betrayed his badge," prosecutor says
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.
