Premise: Even though handgun deaths are actually down a bit from the early '90s, says a piece in Sunday's NYT Week in Review, recent well-publicized shootings tend to stimulate lawful gun purchases for household protection, which may be bad news for those households, since according to one quoted expert, the odds that a home will be the scene of a homicide are substantially greater if there is a gun in the home.

Hypothesis: There will be a rise in handgun deaths as more homes are buying and storing guns.
