You again found those links in the very same gun lobby organization page I told you not to use for very obvious reasons.
The first link is not an article. It's a severely flawed opinion piece from four years ago by an american.
Latest official stats from the UK shows that violent crime has dropped over the last decade.
"Between 1995 and 2004/05 British Crime Survey (BCS) violent crime has fallen by 43 per cent"
and
"In 2004/05, 839 deaths were initially recorded as homicide, a decrease of two per cent on the previous year."
Now to your second link...
And I'll just mention two things about that one. First the "research" was done by "Countryside Alliance's Campaign for Shooting". Secondly that was written way back in 2001. I'll leave it at that.
Again, please do make up your own mind by researching real data and stop listening to the gun lobby. Seriously.
