Interesting organization that CATO is....primarily funded by private donations that are tax deductible, now that in itself is quite interesting since the mission of this organization is to free people from government control, and the government gives them a tax receipt, lol. Their research paper is suppose to be non-partisan but this particular white paper on Tough Targets is authored by two individuals from pro gun states, one authored a book "
How and Why Guns Became as American as Apple Pie" , and the other is a director of PR for the Students for Concealed Carry, yep no bias in that white paper. They tracked newspaper articles over 8 years and came up with conclusions that thousands of crimes are prevented each year by gun owners, but doesn't say how many are not prevented. Last I check there are thousands of gun deaths as well. Hard to critique this paper unless you read all 60 pages, and I'm not paying for it. Wonder how biased a report would be if Bloomberg or Piers Morgan authored it??? Hmmmm, wild guess but I'll bet the farm it will the opposite of this paper. You know full well all these studies are full of holes that will be exploited by the other side.
The other Wikipedia link shows this:
"
The frequency of defensive firearms incidents, and their effectiveness in ensuring safety and reducing crime is a controversial issue in gun politics and criminology.[SUP]

Different authors and studies employ different criteria for what constitutes a defensive gun use, which at times leads to controversy in comparing statistical results. "
This statement confirms that no study can be conclusive in either as there are so many mitigating factors and pretty well what I said above, no study can provide concrete evidence one way or the other.
