Not walking back on anything. All of these stats, the ones I am citing and the ones you are, show correlation. No guns don't cause suicide. They don't cause homicide either. They just make both of them much easier.
What do I make of the Australian study?
As I said upstream, I will show you some stats and you will show me some stats. We can find stats and research to support whatever we want. It is the interpretation that counts. I would have to see the full article to comment, not the abstract.
For now, I will use what my common sense and intuition tell me.
You need to understand stats a little better, and think about what you think you're proving vs. what I'm showing.
You have claimed that guns cause homicide, violent crime, and suicide. You have been able to cherry-pick stats with narrowly selected datasets to support your position.
I have claimed that you are mistaken. All I have to do is show that there are
some places with lots of guns and low crime. Lots of guns and low murder rate. Lots of guns and low suicide rate. Or, conversely, few guns and high crime. Few guns and high murder rates. Few guns and high suicide rates.
Any one of those situations proves that your thesis is incorrect.
You: All dogs are brown. See, here's some stats -- all the dogs in this study are brown.
Me: No, not all dogs are brown. See, here's some black dogs, and some white dogs, and some gray dogs.
You: Well, studies can show anything. I'm right anyway. My studies say so.
You see, if there are places where there are
few guns but high crime rates, it proves that high crime rates can exist independently of guns.
If there are places where there are
many guns but low crime rates, it proves that the presence of guns does not cause crime.
Your stats only prove that there do indeed exist
some places in the world where there's a positive correlation between guns and crime, or between guns and suicide. They do not prove that guns cause crime, or that in the absence of guns crime will always be lower.
My stats prove that your thesis is
wrong. Just plain wrong. If your thesis were correct, there would not exist any place with high gun ownership and low crime rates, nor any place with low gun ownership and high crime rates.
