I'm assuming that the bold part there was in reference to the links I gave? Perhaps you didn't look at them close enough as there are European countries that are worse off than the US.
All I can say is that you really need to start studying up on the problems that are going on over in European countries. Because if you think that they are more advanced than the US democratically...you have been drinking way too much kool-aid.
I think you need to study European geopolitics a bit before you post such drivel. I have been very consistent in describing which countries should be compared for this purpose: advanced industrial countries with similar political and economic systems and history than the US. I specifically identified this as Western Europe and suggested that former communist countries were not comparable. This is clear as countries which are only relatively recently enjoying the benefits of liberal capitalist democracy are not comparable. The Baltic States and Poland for example were gangster states run by authoritarian regimes until the 1990s. Russia, which is of course European when it's major population centers are concerned, still has capital punishment and is still a gangster state.
It's difficult to see how any misunderstanding could be other than obtuse and willful. The challenge to the USAs system of populist barbarism, when it comes to penal policy, is from an alternative liberal model that is practiced in Western Europe. In all those countries the murder rate is significantly below that of the USA. The countries in your survey who are worse than the USA, as I stated, are Latin American dictatorships or former communist countries.
Don't get me wrong. The USA is of course on the whole a civilized country and no country in the world has it 100% right. But it is a country now whose penal system falls increasingly into disrepute. And it is clearly a system that doesn't deliver when compared to its peers. Many things in the USA are better than in Europe: the spirit of enterprise for example. But when clear evidence shows that the USAs performance on an issue can only be better than Columbia, South Africa, former USSR states and Poland, American nationalists just get blinded by a "my country right or wrong" myopia.
The comparability is not based on a tribal rivalry between "Europe" (whatever that means) and America but on the basis of the hypothesis being proposed by me that those countries with well established democratic capitalist models and a more liberal penal policy, do better than the USA when it comes to "deterring" or preventing or avoiding violent crime. The hypothesis defines the comparable countries as Western European, not some silly adolescent Europe vs America rivalry.
And your evidence proves my hypothesis to be correct.
I don't know what you mean about the bold. I'm using the mobile application. As to studying Europe, I have been to and done business in nearly every European country (in West and East) and also the USA (many times) so your rudeness is misplaced. My arguments are not about American "democracy" but about penal policy which is one aspect of democracy ( concerned with individual rights and a particular portion of the social contract that liberal democracies have between governed and governments). You may choose to widen this discussion into a woolly mush of transatlantic name calling. My analysis is precise, focused and clear.
You seek to widen the issue simplistically. On the wider issues of democracy and economic and political policy there is much that can be learned from each other, if chauvinist nationalists could ever see beyond their own blinkers.
