Did guns or vaccines save more lives in 2021?

[Jehanne]

True Gary is a gun nut whose research can't be trusted.

I thought that Gary Kleck was one of the most influential criminologists of all time. He is also famous for his arguments against death penalty.

He needs to specify his null hypothesis more systematically before proceeding to reject it. For instance, in the 19th-century some towns west of the Mississippi River had murder rates far surpassing those of modern-day America; of course, everyone (or, nearly everyone) in those communities was armed. One could frame a null hypothesis to test that unarmed individuals in those communities were at a higher risk of being a victim of homicide than an armed individual, and, therefore, conclude that arming individuals is a good thing.

As Mark Twain said (paraphrasing), "There are lies, damned lies, and, there's statistics".
