I make that 76 percent of Americans buy a gun or guns for some kind of defensive purpose, according to a National Shooting Sports Foundation (NSSF) poll conducted by Harris Interactive. A couple of problems though. First, I think the survey covers the last six months, but it’s not clearly stated. There’s no link to the data, methodology or sample size; I can’t find it on the NSSF’s website and Harris Interactive doesn’t have it on their site, either.
