If a gun control law saves even a single life, it's worth it. As a mathematician, I call this logical fallacy reasoning by incomplete hypothesis.
My favorite example of this form of unreason is the following.
Adolf Hitler's persecution of the Jews drove many of them out of Europe who otherwise would have remained in Germany to be killed in Allied bombing raids. We can therefore conclude that Hitler's persecution saved Jewish lives and was therefore worth it. Note that I've left the Holocaust out of the hypothesis.
