The under reported cases, and death count are easy to pull out of the statistics. The claim you are making with no evidence require no evidence to debunk. It's just a lie.
This is not easy to pull out of the statistics, it is generally not even attempted. The approach has been to not investigate deaths if a test suggests covid in someone's body,
but to simply count it as a covid death. This actually has been openly admitted. I do not have this in front of me, and I do not feel very generous after having been called a liar
