Not the first community...
Kennesaw, Georgia has a similar ordinance. While I don't agree with requiring anyone to own a gun, I guess they can justify it as a public safety issue, kind of like requiring sprinklers, fire extinguishers, or first aid kits. It worked/works for Kennesaw. Despite being a growing city within 25 miles of one of the two most violent cities in the US, their violent crime rate is LOW - the number of crimes hasn't increased significantly despite the population of Kennesaw doubling. They have some of the best public schools in metro Atlanta, too. And some good shopping (malls, etc.) - I like shopping there because I've always felt safe, whatever the time.
Oh yeah - Kennesaw has no intention of enforcing the law, either. I think there's a whopping $25 fine for breaking it, but I've never even heard of anyone being charged. It was more of a pro-gun, anti-criminal kind of "don't mess with us" statement.
