Tell us
About Finland or Switzerland's homicide rate
and gun ownership.
You'll quickly find out that the amount of guns
has nothing to do with murder rates.How come ...
an absence of correlation between X and Y in one instance
proves that X doesn't cause Y
and yet ...
a perfect correlation between X and Y in another instance doesn't prove that X causes Y??
The only response I can think of to your assertion is:
Tell us
About Canada's or the UK's or Western Europe's or
Japan's or Australia's or New Zealand's homicide rate
and gun ownership.
You'll quickly find that the amount of guns has
everything to do with murder rates.
Except, of course, I wouldn't say that.
I would no more say that the number of firearms in a population has EVERYTHING to do with homicide rates than I would say that it has NOTHING to do with them.
The fact that a correlation observed in many, many cases does not bear out in a few others is NOT proof of absence of causality. It may well be evidence of OTHER causal factors at work in the exceptional cases that are not present in the cases where the correlation bears out -- and that counteract what causal effect the high numbers of firearms might well otherwise have.
The thing is that anyone who would deny that the number of firearms in a population has SOMETHING to do with homicide rates -- i.e. says that it has NOTHING to do with them -- is the one really making the assertion that needs proving here.
The strong correlation observed
in so many instances is obvious prima facie evidence that the number of firearms in a population has SOMETHING to do with homicide rates. That prima facie case *does* need rebutting.
Obviously, when investigating causation and examining potential causal factors, one would like to consider
all other things being equal situations and compare outcomes in them. We seldom have the good fortune of finding such situations.
As we all know, one of the "things" that is not "equal" as between the US and other mature, industrialized democracies is that
income disparity in the US is hugely more pronounced than in those other, otherwise relatively comparable societies - and is growing faster than in those other countries (if it is growing in them).
And we know that violence (e.g. homicide rates) correlates positively with income disparity -- the larger the gap between rich and poor, the more violence. Russia and South Africa bear this correlation out, for instance.
A sensible person might look at the situation and say:
Obviously, we can expect higher levels of violence and crime in societies where more income is concentrated in the hands of fewer people than in societies where income is more evenly distributed.
Obviously, any propensity to violence and crime will be exacerbated by ready access to effective, efficient and low-risk means for committing violent/criminal acts.
One might tentatively conclude: In a country in which one condition (extreme income disparity)
is not present, the number of firearms present will have a relatively less significant causal effect on homicide rates. In a country in which that condition
is present, the number of firearms present will have a relatively more significant causal effect on homicide rates. One way to test the conclusion would be to find countries with high income disparity and low numbers of firearms, and see how they compare. Unfortunately, we can't just order up guinea pigs in this experiment.
Other factors will certainly have to be considered in determining what other factors exacerbate the tendency and what factors mitigate it: the content of laws and the effectiveness of law enforcement, for instance, need to be compared as well.
A person who gives a shit will then set about identifying, assessing and selecting effective and acceptable ways of reducing violence and crime in a particular situation.
A person who doesn't will keep demanding that the other side "prove" its case.
As the groups opposing a constitutional challenge to some of Canada's firearms control legislation said in 2000:
http://www.guncontrol.ca/Content/ConstitutionalChallenge.htmlWhile the Alberta Government claims that there is no "proof" that gun control works, the standard of "proof" it is demanding goes far beyond what is required for justice reforms. Dr. Neil Boyd, Criminology professor at Simon Fraser University argued that the detailed evaluation of the 1977 legislation provides stronger evidence of the effectiveness of gun control than is available to support on most other reforms. Dr. Martin Killias, criminologist, University of Lausanne, has suggested that demands for conclusive "proof" are often a strategy for delay.
While we're there, here is those groups' comments on the right wing's darling, Prof. Gary Mauser (of the Fraser Institute and past discussions here):
Alberta’s case also relies heavily on the work of Gary Mauser, Professor of Business Administration at Simon Fraser University and pro-gun advocate with the BC Wildlife Federation. The methodology used in his study on arming for self-protection was challenged in the sworn affidavit of Jens Ludwig, Assistant Professor of Public Policy at Georgetown University. Mauser’s research has been funded by the National Rifle Association (NRA) and the Langley Symposium, a pro-gun organization. Alberta’s expert on domestic violence is Senator Anne Cools <no comment needed for Canadians - a stupidly and viciously anti-feminist politician who has waged war on behalf of "men's rights" for years ... and who is, gosh, a black woman>.
Funny how the "pro-gun"/right-wing (Govt. of Alberta, Fraser Institute, Anne Cools ...) correlation bears out so well in Canada too.
