But that is not correct. I have carried a knife pretty much every day of my life and have never used it in a fight. I have carried a gun for at least 30 years, and I have never used it. My wife has carried for the past 10 years. Never used it. My mother carried a gun her entire LEO career. Never used it. Two of her brothers were also cops. One did shoot a guy, after the bad guy fired at him. That brother had a son who followed him as a LEO. Never used his gun. One of our sons and a son-in-law are cops. One of them shot a murder suspect who came out of a house trailer with a shotgun. Four of our non-LEO kids also carry. Never used them.
So two out of twelve in my immediate family, both wholly justified. There are 500,000 people in Colorado with concealed carry permits. There are over 20 million people in the US with concealed carry permits.
The number of violent crimes committed by CCW holders is miniscule. A study done by the "Violence Policy Center" (an anti-gun organization) collected a bunch of data. They identified 1,335 gun fatalities involving a CCW holder. After eliminating the deaths in which a CCW permit was irrelevant (such as suicide or crimes in their own home - both of which are terrible things, but neither has any bearing on CCW permits) they were left with 801 fatalities involving CCW holders that were determined not to qualify as self-defense. 801. That is all. Oh, did I mention that the data covered a fifteen year time span?
It's not looking good for your claims...
