It is a fact that dead guys are not repeat offenders....okay....but not all people shot as a matter of self defense are dead guys.
Your example is interesting, but show cause and effect. How do you know why he hasn't been burgled again? How he done other measures to his home? Has the crime in the area changed?
It is like the example I noted above about Texas getting its CHLs. It scared off the criminal element so badly that is caused crime to drop a couple years prior to the inception of the CHL program and even cause crime to drop in states where concealed carry either wasn't allowed or was highly restricted were more than 1000 miles distant!!
In other words, something else was going on at the time to cause crime rates to go down that had NOTHING to do with the CHL program.
People like to point out Florida as a great example of where the violent crime rate went down the year their concealed carry program went into effect...as if criminals all of a sudden realized that everyone became magically armed. Strangely, the crime rate in Florida went up in the following three years after that! So much for guns reducing crime.

The same holds for Texas in 1996. It is lauded as showing a remarkable drop in crime when CHLs were allowed, but then again, crime dropped in some 43 states in 1996, including some that did not have concealed carry or that were anti concealed carry. What does that tell you?

It should tell you that something else is at work other than concealed carry.
The notion that concealed carry drops crimes rates, especially violent crime rates, is pretty silly. It is a lot of wishful thinking and rose colored glasses.
Concealed carry does not affect the overall crime rates or overall violent crime rates in an appreciable manner, or it hasn't so far. It does have a tremendous effect for those individuals who do carry and defend themselves however. That is where the real power of this comes into play and why folks carry.
