This reminds me of one of my favorite (due to its uniqueness) local laws in the US:
> In Kennesaw, Georgia, local law says that “every head of household residing in the city limits is required to maintain a firearm.” “If you're going to commit a crime in Kennesaw and you're the criminal – are you going to take a chance that that homeowner is a law-abiding citizen?” asked Kennesaw Mayor Derek Easterling
