Of particular note was this. Of course they are taking into account all violent crime and not just "gun crime" as the anti-gunners tend to do:
The U.S. has a violence rate of 466 crimes per 100,000 residents, Canada 935, Australia 92 and South Africa 1,609.
Some interesting numbers there. The US, being saturated in guns, has a lower "violence rate" than it's equally gun-saturated, yet more restrictive neighbor to the north. However, the island nation of Australia has a much lower violence rate than the island nation of the UK, despite their similar gun laws. Even more interesting is that the French are apparently more violent than the Americans. I guess I better think twice before making any jokes about selling French WWII rifles.
So what's the moral of this? If you want to be "safe" either live on a homogeneous island or let law-abiding people arm themselves.
