After this post I will not debate you about training. But I think you need to know more facts. Hope you enjoy the read.
I wasn't debating you about training, or even comparing accident rates between cops and CCW holders. You missed the point - there isn't even a minimum level of safety training necessary to CCW.
I made a very salient point that on private property, the property owner has ultimate moral and liability responsibility for his guests.
When the owner allows people who he has no idea what their competence level is carry, he's taking on the employee's liability and giving up his moral responsibility to control the safety related things on his property he has the ability to control.
When his dishwasher drops the pistol that he's been carrying on half cock (like some TFL members do) and shoots someone - the owner is going to pay the greatest price (aside from the dead person) and could have prevented it.
That's what you keep dancing around.
The reason you're avoiding the real question is that you, like many firearms enthusiasts, believe that firearms are the only solution to every safety problem. But firearms are not the only "arms" one can carry, and firearms are one of the few arms that do have a real danger to bystanders when mishandled. A baseball bat will also get you back to a parked car at night, but won't "just go off".
When an a business or property owner says "Don't bring a gun here", they are doing the only practical thing they can to prevent people who don't know how their gun works from killing someone at some point in the 2000 hours a year they spend at work.
And before you post more statistics at me,
I have nearly been shot - twice - by "gun people". I'm a gun person, I like the sport and have carried for protection. If I owned a store, I would have to know the skills and equipment of any employee really, REALLY well before I let them bring a loaded gun to work. Because if they did hurt someone, I'd bear the guilt, shame and loss of income and property that would result from MY decision to have questionably trained shooters working in my store.
I challenge you to address the moral responsibility of the owner to avoid employee negligence in your next post.
