Re: Erm, what about...
Actually we in Australia do have somewhat stricter censorship of video games. We can't have games where drugs are a positive impact on gameplay, or shootemups where bodies pile up, and some other various slightly random, but basically understandable limits on just how over the top games can be. We've had several AAA titles banned from sale in Australia over the years as a result, and every now and then there'll be a title that has an "Australian" version just toned down for our ratings system.
We also have pretty tight gun controls. We don't have mass shootings (for decades now) after we took the guns away from most people after the Port Arthur massacre. People often point to that fact as proof that means + motive + opportunity is still the basic formula for crime, and limiting access to the means has a direct impact on the body count.
We have our share of people with grievances and people with stability issues, but we manage not to kill kids at school.
Oh, and I've been to Kentucky and it's a dump. QED :)
