How can you be so sure that some who had a pre-existing underlying condition wouldn't have died from it, rather than a coinci, adental case of COVID? Did people suddenly stop dying from said conditions once COVID arrived? Will they go back to dying from them once (or if) COVID ever goes away?

Thankfully, at least gunshot victims aren't being listed as "COVID" deaths.

Er...oh, shit:
