Whether you agree with Obama's stance on gun control or not, he is unequivocally right about one thing: Mass shootings do not occur in other industrialised nations with the same frequency as they do in the United States.

To do a fair comparison, you need to control for several other factors. Did you?

• Ratio of US population size to the other industrialized nations.
• Degree to which each nation is targeted by mass shooter ideology
• The total exposure to violent"cultural" products from Hollywood.
• The percentage of events that don't count because they took place in gun free zones - places that emulate the exact conditions you are advocating.
• The number of fewer fatalities that would have occurred if 10% of the population in each of those shooting galleries had been trained and armed.

I'm sure there are other factors - but you get the idea.

I would argue that your statistics are skewed in favor of greater losses precisely because of the thoughtless restrictions that have already been placed on our ability to defend ourselves.
