The writer is incorrect. Although Mr. Garner lay motionless, he was alert and responsive, telling the onsite EMS (it took approx. 3 min) he couldn’t breath. He was breathing when he was put into the ambulance.
On the way to the hospital, he suffered cardiac arrest, and died.
No choking, no asphyxia, no hypoxia, no strangulation.
I’ve read that too, but good luck getting anyone to pay attention to the information. And how would this representative know more than the GJ to say he sees something more “clearly” than they did?
