Many guns produced today do not have safety devices such as loaded chamber indicators and magazine disconnect devices, for which the technology clearly exists. Deaths caused by the discharge of a gun, when the person did not know it was loaded, are particularly tragic, in that they are so preventable. Laws governing the design of guns in no way invoke the rights that some believe they have under the Second Amendment. All I hear is how there are background checks for anybody to buy a gun. I don't see the purpose or effectiveness of these checks especially since these guns are still making it into the hands of kids.
Background checks are valuable, but imperfect.
We do not yet have an adequate data system to determine instantly whether someone has a felony record that would disqualify him from legally purchasing a gun. The law proscribes the sale of a gun to someone who has been adjudicated mentally incompetent, but we cannot check whether this has taken place. Thus, guns frequently get into the hand of those who should not have them. Your question pre-supposes that the valid interpretation of the Second Amendment is at odds with the opinion of policy persons such as myself. As someone who has been a lawyer for thirty years, I disagree with your basic premise.
