Why?
Inescapable "reasonable doubt" hangs over it all. How much did he swallow? What separates an asphyxiation heart attack from an overdose heart attack? Lack off bruising? Being able to say something over and over again while apparently not being able to breath? What happens wjen you restrain an anesthetized individual?
That's not my opinion as much as the thing that takes away the "beyond" part that precedes "reasonable doubt" going into a Jury's decision.
Unfortunately, there will be no objective way to hold that position "in the event of".
This will be insane if a conviction fails to get leveled. It may not even be advisable to share if you agree with the decision of that impartial jury if that should happen. It will get that polarized. This is also the TOP "white supremacist" argument, so bear that in mind.
That's all worst case scenario (for law enforcement everywhere). But with all the cops and doctors testifying for the prosecution America may yet escape civil unrest. Especially the part where he is dead for 4 minutes before they stop "restraining" him..
Still. This is from the medical examiner's report.
Blood drug and novel psychoactive substances screens:
1. Fentanyl 11 ng/mL
2. Norfentanyl 5.6 ng/mL
3. 4-ANPP 0.65 ng/mL
4. Methamphetamine 19 ng/mL
5. 11-Hydroxy Delta-9 THC 1.2 ng/mL;
Delta-9 Carboxy THC 42 ng/mL; Delta-9 THC 2.9 ng/mL
6. Cotinine positive
7. Caffeine positive
And this from a medical dictionaries entry for Fentanyl:
The recommended serum concentration for analgesia is 1–2 ng/ml and for anaesthesia it is 10–20 ng/ml. Blood concentrations of approximately 7 ng/ml or greater have been associated with fatalities where poly-substance use was involved. While fatalities have been reported after therapeutic use, many deaths have occurred as a result of the misuse of pharmaceutical products
