The number of small arms in civilian hands, worldwide, is staggering. Even if the UN treaty regarding small arms were to be approved by all members (it won't, and not just because of the US) there would continue to be a fantastic number of small arms in civilian hands.

A lady on the bus during my recent visit to Ireland told me that she was Canadian, "...and Canada has the highest per-capita number of guns in the world." Then she showed my a picture of herself at a shooting range using a military type of rifle with an underslung grenade launcher attached.

That is most assuredly not a hunting or target weapon! (It won't stop me from visiting Canada, however.)
