I can defend myself against a knife-wielding maniac with a gun far better than I can defend myself against a knife-wielding maniac with .. another knife.

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.
