I have summarized my findings of Floyds autopsy and toxicology report in a way that I think is incontrovertible.

It is as follows, feel free to copy and paste freely if you want

According to Floyds autopsy and toxicology report, Floyd had a large amount of fentanyl (downer) and methamphetamine (upper) in his system.

Meth causes an increased heart rate, which increases blood/oxygen flow throughout the body. Fentanyl, on the other hand, suppresses breathing, which decreases oxygen intake.

This causes a lack of oxygen to flow throughout the system due to the suppression of your pulmonary system.

This leads to an inability to "catch your breath". An inability to breathe, in other words. After a short while, it leads to cardiopulmonary arrest and subsequent death.

To top this off, the autopsy also showed that Floyd was already close to catastrophic heart failure due to his drug intake over time and a 98% occluded artery, meaning 98% blocked.

Put this all together and you have cardiopulmonary arrest as the cause of death. What did his autopsy list as cause of death? Cardiopulmonary arrest.

Ladies and gentlemen, George Floyd died of an overdose from a very bad combination of drugs.

Furthermore, for death from manual asphyxiation to occur (which is what they're trying to say took place), enough pressure would need to be applied to the neck that it would cause subdermal bruising in the neck, along with other slight damage.

No such damage was found in the autopsy, so manual asphyxiation due to a knee on his neck could not be the cause of death.
