What if"?

What if…? What if the number of Coronavirus cases is not accurate and is actually exaggerated by many times? What if the estimates are based on a flawed computer model? What if the developer of the model has so admitted? What if the death certificates are being modified to show more Coronavirus related deaths than actually exist? What if people who were already dying of serious conditions like heart disease or diabetes or COPD are now being counted as Coronavirus deaths because of the supposed presence of Coronavirus at the time of death? What if hospitals are assuming people have Coronavirus just because they exhibit one or more symptoms, like a cough or fever, even though no actual lab testing is performed (presumptive diagnosis)?
