This would more accurately be referred to as, "Alberta Gun-advocate's Take On It". The fact that he is a doctor seems kind of irrelevant since he is using publicly available research to make his case. He is not a researcher, and does not claim to have extensively researched this issue.
Alberta is generally pro-gun, and also a very very safe province - there is little crime, with or without guns, so extrapolating the stats he is talking about to the rest of Canada, much less the US, is a bit misleading.
Rod's numbers cunningly quoted just accidental gun deaths. What about intentional gun deaths (murder and suicide)? Then compare that number with the # of intentional deaths caused by doctors (murder and assisted suicide).
