It is an interesting postulation and I imagine one that excites demographers and crime statisticians, especially if you widen the question and compare rates of such offenses across a whole board of different legal frameworks for gun ownership.
However I would like to suggest there may be a fly in the ointment, especially looking at Dizzy's original comparison between us and the United States of America, while gun ownership in this country may well make me feel safer from muggings, it sure as hell will make me worry much more about getting my fucking head blown off!
Unfortunately it seams that the last time the UN statistics had explicit information about gun homicide for comparison was 1999, but I have included the last comparative figures on gross homicide rate as well, these show that while we have seen a slight increase America has had a reduction in the overall rate.
