In this case it wasn’t “cardiac arrest” it was asphyxiation causing a lack of oxygen to the brain. When the brain stops, the heart stops.
The point was, one of the other policemen helping to hold him down said there wasn’t a pulse. That’s cardiac arrest.
To jonrick46.. you said.. “When the brain stops, the heart stops” so when a person is ‘brain dead’ and just laying there in the hospital bed, the heart has stopped right?, I’m not understanding this. Wouldn’t the body start decomposing? Anatomy of the body is some weird shit.
