No it doesn't. But do you doubt that with this right comes the duty to get training. I don't have any problem with the purchase of a firearm being a private matter, but if you're going to carry, concealed or otherwise, you need to be trained and counseled on what is going to happen to you if you shoot someone, even in self defense.
The problem with modern firearms ownership is the anonymity of the possessor. A hundred years ago the people of a town knew who the whacko's were and would boycott a general store that sold a pistol to the town nitwit.
No, with rights come duties, and it is in your interest and in the interest of the 2nd. Amendment, that those who exercise this right seek the knowledge about it.
What you are proposing has nothing to do with firing a weapon. You're not concerned with muzzle control or hitting your target. You're worried people will not understand you will be sued by any surviving member of this persons family or a bystander who witnessed the shooting. Do people need to know what will happen to you when you fire a weapon to defend your life or the life of another. Hell No! If your life or the life of another was in danger would that knowledge be of any use to you? No!
Nobody needs that type of training. We do need a law that says if someone is committing a violent felony and is killed in the process nobody can sue as a result of that action. We need a law that says if someone breaks you’re your home and you kill them then you get a commendation from the Governor.
Now most semi-intelligent people are going to realize that they can currently be sued in this circumstance but in a life threatening situation what good will that information do them? Are they going to let themselves or others be killed because they may be sued? No!
