An outside expert testifying at the George Floyd murder trial against Derek Chauvin trial said on Wednesday, Chauvin used deadly and excessive force at the time when no force should have been used.

Jody Stiger, a police specialist on the use of force, told the court that the video shows Chauvin applying a “pain compliance” procedure by pulling the 46-year-old Black man’s wrist into the handcuffs.

He said it is hard to breathe in that position even when one is handcuffed. “When you add bodyweight to that, it just increases the possibility of death,” he added.

When asked directly about Chauvin's action he responded saying,  “My opinion was that the force was excessive.”

Stiger also told the jury that using that technique for so long is deadly. “At that point, it’s just pain,” he said describing the Pain Compliance technique.

He also questioned if Floyd's offense (allegedly forging a $20 bill) was any reason for him to be confronted with the deadly technique.

“The pressure that was being caused by the bodyweight would cause positional asphyxia, which could cause death,” said Stiger.

Derek Chauvin, a white ex-police officer, is facing accusations of murdering a black man, George Floyd. He has denied charges of second– and third–degree murder, and manslaughter, over Floyd’s death last May, which prompted mass protests for racial justice across the US and other parts of the world.
