(More violent knife crime, though. This goes ignored by the anti-gun nuts.)
But the crime still rolls on, regardless. Knives don't kill people - violent maniacs kill people. They also injure, maim, disfigure and disable people.
And the UK is no good at dealing with insane maniacs, just because they banned guns.
I'd much rather defend myself with a gun against a knife-wielding maniac than, you know .. get my shit all cut up to hell.
So, just keep that in mind in the equation. Knife crime is absolutely heinous in the UK - it does not get the attention it deserves.
Banning guns didn't fix that. Just made it harder to defence oneself against a blade, which is part of the UK policy - the individual is not allowed to defend themselves, and must depend on the state for that service .. and then only when its severe, i.e. likely to get a politician in trouble.
Check the stats, down-voters: the UK has one of the worst statistics for violent knife crime trauma of all the western nations. Its nothing to be proud of.
