The prosecutors closing argument is having Dr. Tobin declare Floyd's O2 level was 98% when taken at the hospital... to discredit the carbon monoxide theory.
Is that normal for an asphyxiation victim? To my laymind, that would imply the lungs were working until the point the heart wasn't.
Prosecution: Lack of O2 was the cause of death directly as a result of the deadly prone position.
Defense: CO could have contributed to his death.
Prosecution: Nah, he had plenty of O2 which means he couldn't have had significant CO because they bind to the same hemoglobin!
