Are a significant number of reported Covid-19 deaths simply deaths from other causes that were moved to the Covid-19 column? From Ethan Young at aier.org:

[Editor’s note: the article and video discussed below have been pulled by Johns Hopkins Newsletter. You can read the announcement here. An additional explanation is here. The claims made by the economics professor will clearly require more investigation, as the announcement says. That said, AIER is publishing this in the interest of objective science and open discussion.]
At the time of this writing, the United States currently maintains the highest number of Covid-19 deaths and ranks 11th for the highest deaths per capita. There have been approximately 262,000 recorded Covid-19 deaths in the United States, which is certainly a concerning number.
However, a new study (link removed or site crashed but now available at Archive.org) published by Dr. Genevieve Briand at Johns Hopkins University notes some critical accounting errors done at the national level. The study – which is still being vetted – simply examines the raw data that should have been questioned months ago. The overall conclusion is that Covid-19, at least according to collected data, is not the killer disease that it is currently hyped up to be. AIER is not endorsing the study as is without further study, but we are interested in the argument being examined and discussed.
