The majority of firearm incidents (discounting suicides) is with illegal firearms (70 percent).  These firearms are largely smuggled in from the USA, who's Republican congress has actively passed laws preventing their law enforcement from being effective against gun smuggling. 
The author states that comparisons aren't a decent way of determining how well we are doing, then goes on to make comparisons with other countries at how well we are doing.
So which is it? Are comparisons valid or not?
Note that Iain Overton fails to give any suggestions.  Canada already does as much as Germany, France, Italy AND Australia on firearm regulations.  Like Australia, Canada already did many "hand in your guns please" amnesty events and revised it's regulations. Like Canadians, Australians can still own guns. Of course, Australia, Germany, France and Italy don't share a porous border with the USA, a country awash in guns.  Comparisons to Europe and Australia are misplaced at best. Try Mexico instead.
