"...poor attempt at treating the symptom rather than the disease". Sorry, the symptoms (i.e. lots of people dead) are the problem here.

My data pull was primarily for the countries mentioned earlier, I added some others I find relevant because I have experience living there (never been to Finland). I did not imply the US was #1, the extract was obviously a very short one.

The Wikipedia page you cite tells essentially the same story as the Washington Post article: of the OECD countries, the US is by far the most violent, more than 4x more than Germany, for example. Take a look at the countries surrounding the US in the statistic! If you're not embarrassed, you're not paying attention.

The "would not have been possible without a gun" argument is specious, as is "anyone sufficiently determined" argument for suicides: you are assuming that anyone with a suicide attempt is sufficiently determined, as is someone wanting to kill someone. This is a fallacy, both logically and from what the data show.

Not being able to stop everyone is no excuse for not even trying to stop those that can be stopped (or reducing the damage...heck if no-one gut hurt, would the "rampage" even be a problem??)
