A similar incident happened a few years ago close to where I live: In that case, a man was accused of loitering outside a store. By all accounts, the guy was a regular customer, and the store managers didn’t mind him standing there. But, this time, a police officer happened to be at the store, and when he came walking out, he confronted the guy.
To make a long story short: The officer tried grabbing and pepper spraying the man to arrest him. A few customers came out to help the officer pin the man down. Then backup arrived. As the whole crowd was putting the man into the patrol car, they realized he wasn’t moving. Autopsy results showed that he was killed by asphyxiation.
There was a man on Utube who was asphyxiated during a traffic stop by two cops. He kept telling them he could not breathe. Then he didn’t.
