AS, may I ask where you pulled that from?
The United Nations.
They were looking at practical ways to disarm the natives and were trying to determine if it was worth it.
Know what else you should take a look at?
A 2001 report heralding the success of disarmament programs in El Salvador, Mali and especially South Africa. If there is a smoking gun to idiocy there it is.
Now that the rapists (literally) are in charge of South Africa... lets just say that the US is in no danger of overtaking them in per capita.
