1. The fact that Floyd could speak, indicated his airway was not blocked. The primary sign of choking on food is the inability to make any speech.
2. If Floyd’s carotid arteries were blocked by pressure on the knee, he would’ve passed out within less than 30 seconds, not 8 1/2 minutes.
3. Primary symptom of opioid overdose is the feeling of not being able to breathe.
All three are established facts.
