I think he knows that. He is saying that CDC is having trouble determining CoD from the death certificates because they usually list the complication rather than the disease as immediate CoD. And that the doctors who do this aren't being fraudulent. They are just using the standard procedure for what to list as CoD.That is a good point, but keep in mind that many of those complications would NOT appear if they didn't get COVID.
The analogy that I use is someone getting in a car crash, but not dying at the scene. What will be the cause of death? trauma? internal hemorraging? stroke because of blood clots?
In the end, however, none of those things would take place if the accident didn't happen.
