I hear your point, culture and education certainly play a significant role in shootings, but to believe that they're more important than people easily getting a gun seems obtuse.    

 The ease of access to gun ownership in the developing world is nowhere close to to the US fyi.

You could make a pretty good arguement that access to guns is part of American culture. It's beyond a law/right at this point and is part of many American's cultural identity.
