Of course there is a difference between an extending dog lead and a gun but you are using the exact same argument to justify your extending lead as the gun nuts use to keep their AK47s. I use the same point to argue against both. It is not the fault of extending leads, guns or people. It is putting something that can cause damage in the hands of idiots. And in both cases it should be subject to regulation. There are degrees of course but the principle is the same. Don't let those who cannot handle them play with dangerous toys!
