First of all, the second amendment does not need to be incorporated. It stands on its own two feet. It is an individual right both enumerated and guaranteed to all Americans in good standing. And second of all the 14th Amendment worshippers would be wise to find another deity.
Ever wonder how a city like New York or Chicago can ban the ownership of guns?
They can't, it's unconstitutional.
The U.S. Constitution was written for what reason?
a) To define the powers of the new Federal Government
b) To define the powers of all the states
c) To define the powers of both the states and the new Federal Government
d) To define individual rights
Correct answer: a
The Constitution defined federal powers only. Each state already had their own state constitution. The second amendment said that the federal government shall not infringe the RKBA.
With the exception of (I believe) six states, each state has their own "second amendment".
