Sentence:1 - A criminal in possession of a weapon DOES NOT have a gun for the same reason I do. Unless you are implying that I have guns to commit crimes. Sentence:2 - My conversation with @tampajack1 was not in relation to the availability of guns, but the ability to bear arms in public places.
1. You're misunderstanding my point. I was saying that the reasons it is relatively easy for you to get your hands on a firearm are also why it's relatively easy for criminals. The more available guns are, the easier it is for them to end up in the wrong hands. 2. I imagine many criminals carry guns for protection too.
Yes, the entire Bill of Rights was about either limited the federal government's power or stating what powers it didn't have. That changed following the Civil War when our government overwent a radical makeover and we passed the Reconstruction Amendments. But the point of selective incorporation (which is what has made parts of the Bill of Rights applicable to the states) is that the right has to be compatible with being applied to the states (in addition to the other parts of the doctrine). The Second Amendment is incompatible with being applied to the states. Because applying the Second Amendment to the states gives the federal government exactly the power the Framers created the Second Amendment to prevent. In other words, incorporating the Second Amendment runs contrary to its purpose. That's not true of the First Amendment, for example.
