This is an interesting story on several levels. Gallup finds that 63% of Americans over all think that owning a gun makes you safer, and the breakdown is interesting: 81% of Republicans think so, 64% of Independents and 41% of Democrats.
But only 42% in total admit to having a gun. I've remarked on that before. It is a question with built-in underreporting. If someone calls you on the phone asking you if you own guns, you have every reason to lie. You could be talking to a thief, a government snoop of some sort, or some busybody from the political ax grinder contingent.
