But there's more at stake than general crime figures anyway. In the UK we've got a choice (or we would have if major changes ever became a serious possibility instead of a hypothetical one brought up by curious Americans...). We can either keep the existing laws, which stop us from having to worry about intruders and attackers having guns. Or, we loosen them, which would allow us to protect ourselves which much more effective weapons but would simultaneously make it many times more likely that criminals would themselves have and use against us those same weapons. To my mind, the latter would be pointless. You've got a greater chance of surviving a confrontation with the kinds of weapons and makeshift weapons you can keep in your house already than you have of surviving a gun fight. Why would we introduce a much more deadly threat into our lives? To make us safer? How, exactly, would it do that?
