"AED readings are important. Shock versus no shock" - this is basically allowing them to go one of two ways "Shockable", then they weren't 'fatally' injured by the Taser, and external circumstances caused the death. "No Shock Advised", well, they must have had a heart defect. Never mind that there are multiple rhythms beyond VF (Ventricular fibrillation), VT (Ventricular tachycardia) that can be recovered.
The next three are basically trying to imply typically drug use interfered with cardiac activity and that, not the Taser, caused the cardiac event.
It's basically "here's a laundry list of things that can exonerate Taser. Collect them."
