He was talking about having trouble breathing while he was walking to the car.
Yes, it was actually a rhetorical question intended to politely stimulate Colorado Tanker’s thought process.
Exactly. I have read that in every report. I believe Floyd’s efforts in resisting arrest and fighting the four police for 10 minutes that were trying to get him in the car probably initiated his cardiac arrest, along with being high on a combination of the worst possible drugs and a bad heart. At that point is when Floyd apparently said he couldn’t breathe and not when he had to be restrained on the ground IMHO.
