Why are their so many murders in America?

Michael Moore is a filmmaker. You probably know him from the documentary Fahrenheit 9/11. Some of you may even have seen Bowling for Columbine in which he discusses gun violence. In this documentary Moore shows footage of the events at Columbine as they happened, shows the lack of concern by National Rifle Association (NRA) president, Charleston Heston, after the Columbine incident (he held a "gun rally" ten days after the shootings amidst the grief of the community) and another school shooting involving a six year old that shot a fellow classmate (he also visited town shortly after the shooting incident). But that is not what I would like you to discuss as you can tell from the title. In the documentary, Moore continually asks a question. Why are their so many shooting deaths in America? Before answering consider that other answers provided and examined were America's bloody past, easy access to weapons, lax gun laws, etc., etc. However, consider that Japan is the world's leading producer in violent video games, Germany probably has one of the most bloody pasts with Hitler's regime killing over 12 million people during WWII, England's imperialism killed many in other countries, and France also killed their share with imperialistic activity. Yet, Japan has, on average, 39 gun deaths a year, Japan--39,Germany--381, England--69, France--less than 20, and America--8,254. So with the numbers, Why are their so many murders in America?!!!
