Why do you think access to kitchen knives was restricted in the UK? When people stopped having access to guns they started using knives for crimes. Guns have legitimate uses for self defense. What the object is made for is irrelevant, anything can be used to kill someone.

The point I was trying to make was that when guns were banned in the UK people started using knives to commit crimes. Then they restricted access to knives too. Then they installed cctv cameras on every corner. This is not the type of world I would want to live in.
