Yes, whether the police officer committed a particular crime is a matter for the court, not a forensic pathologist. What the evidence tells us, according to a forensic pathologist, is that while Geoge Floyd's heart problems and the drugs in his system made him more vulnerable, they weren't the cause of death.
It's interesting to read that Floyd's body contained "lethal levels of fentanyl". I found
a comment on this by Carl L. Hart, a professor of psychology and psychiatry, who wrote that:
He also had 11 nanograms of fentanyl in his blood. That number, in and of itself, doesn’t tell us much. Immediately after a person dies, the blood concentration of fentanyl increases significantly, so knowing only the post-mortem amount does not tell us about Mr. Floyd’s level of intoxication before his death.
What’s more, the same amount of fentanyl that produces euphoria in a tolerant user can result in an overdose in a newer user. That’s why, along with the toxicology report, we have to look at Mr. Floyd’s behavior shortly before his death.
Videos show Mr. Floyd behaving rationally and appropriately, considering the circumstances. When officers asked him to get out of his car, he did not seem drowsy or lethargic, which is how people high on opioids behave.
Also, the lethal dose of fantanyl is said to be 2 milligrams (
Oxford Treatment Center). A
unit converter says that 2 milligrams is equal to 2,000,000 nanograms - that's a lot more than 11. (Maybe someone read that he had 11ng of fentanyl in his blood and mistakenly thought that it said 11mg? That would be an understandable mistake, as ng looks similar to mg).
