Now Brain....you will find the CATO methodology familiar.....they did what you pointed out in the study of stories in the site... "The Armed Citizen" except they culled through 5,000 stories in papers, not just those picked out by "The Armed Citizen" ....and here is some of what they found....
I just picked up a copy of "Tough Targets" from Amazon......
Disarming the Myths Promoted By the Gun Control Lobby - Forbes
For these reasons, the Cato researchers investigated published news reports which much more often reveal how Americans use guns in self-defense.
The data set is derived from a collection of nearly 5,000 randomly selected incidents published between October 2003 and November 2011. Still, the authors also recognize limitations with this approach, since many defensive incidents are never reported by victims, or when they are, never get published. In fact, the overwhelming majority of the successful self-defense outcomes are those where the defendants’ guns are presented but never fired.
Most of the actual self-defense shootings in the Cato study didn’t involve concealed carry licenses, but more typically had to do with responses to residential invasions. Of these, 488 involved home burglaries. In addition, there were 1,227 incidents where intruders were induced to flee the scene by armed inhabitants, circumstances that might otherwise have resulted in injurious assaults including rapes and murders. There were 285 news accounts indicating that the defender had a concealed weapon license, which in the majority of these incidents took place outside a home or place of business. Pizza delivery drivers were common robbery targets.
Whereas gun control proponents often argue that having a gun put people at risk because a criminal will take it away and use it against them, it seems the reality is more often to be the reverse situation. The Cato data contains only 11 stories out of 4,699 where a criminal took a gun away from a defender, but 277 where the intended victim disarmed the bad guy, although the authors acknowledge that these event reports may be printed more frequently due to newsworthiness.
Still, it should also be remembered that the threatened party often has more motivation to fight back than a criminal hoping for an easy score. There were 25 news reports where armed rape attack victims ultimately got the upper hand, and 65 where this occurred in carjacking attempts.
Then there is the argument that more private gun ownership will lead to more accidents because the average citizen isn’t sufficiently trained to use a weapon defensively. While gun accidents do occur, the Cato study indicates that they are the most overstated risks. There were 535 accidental firearms deaths in 2006 within a population of almost 300 million people. Although every lost life is tragic, the proportion is not particularly startling.
On the other hand,
Newsweek has reported that law-abiding American citizens using guns in self-defense during 2003 shot and killed two and one-half times as many criminals as police did, and with fewer than one-fifth as many incidents as police where an innocent person mistakenly identified as a criminal (2% versus 11%).
Finally, on the subject of public safety, just how well have gun bans worked in other countries? Take the number of home break-ins while residents are present as an indication. In Canada and Britain, both with tough gun-control laws, nearly half of all burglaries occur when residents are present. But in the U.S. where many households are armed, only about 13% happen when someone is home.
