In the UK knife crime is a big issue for those in poverty or those in struggling cities. Having access to weapons of course increases risks of people dying ot those weapons, but removing guns isn't going to just convince everyone trying to lash out to just lie down and suffer in silence.

I don't live in a contry with civilan access to guns, and I don't live in a situation where I feel the need to protect myself with weapons, so I'm not gonna stake a claim in the gun control debate. But if you ban every weapon ever conceivable, without addressing why people are becoming violent to begin with, people will just result to using their own hands (or perhaps more realistically, going above the legal means. Like with Shinzo Abe's assassination).
