As I've just pointed out on another forum, laws of themselves are useless. They are just words on paper. It's the enforcement of laws that produces results. Firearms laws in the UK are firmly enforced, and there are severe penalties for misuse of firearms, whether legally-held or otherwise.

When mass-shootings took place here, the government took strong action. The prudence of those actions is borne out by the fact that there has not been a mass-shooting incident here since 1996 - twenty-one years.
