Dan,
The key there is TRAINED to arms. I do not have a problem with citizens carrying guns (Known as CHL for a concealed handgun license) but again they must be properly trained in not only firearm safety but the laws of the land regarding the use of deadly force.
I know GP has already responded to your post, but wanted to add to his response.
I believe all states should have a reasonable requirement of ability and knowledge to issue one the right to carry a concealed weapon. In Virginia, there is a reasonable requirement.
I'll post this portion of your sentence again for clarity:
but again they must be properly trained in not only firearm safety but the laws of the land regarding the use of deadly force.
What are "the laws of the land regarding the use of deadly force"?
I consider the law of "my land" to be as much force as is necessary to protect my family and myself from idiots that wish to do us harm.
Do you wish to define the "laws of the land regarding the use of deadly force" as you see it?
I have carried a concealed weapon for over 20 years. I have never had to use it, but I revealed it on one occasion to subdue someone. I am proud that I have been able to carry that long and have never felt the need to draw. If I were to draw, I am confident that I could pull the trigger.
I am glad and proud that the American people can afford to pay for a police force and for the military to help protect them, but protection starts at home.
We protect ourselves, and call for you if we need help.
Have fun,
Phil
