Wrong the 2nd is incorporated States can not violate the 2nd any more then any other part of the Constitution. States rights only apply to those things not controlled by the Federal Government.
Wrong.
The Second Amendment is incorporated to the states by the 14th Amendment. See:
McDonald v. Chicago (2010).
The issue has nothing to do with ‘states’ rights’ or what can or cannot be ‘controlled’ by the Federal government.
A given state can no more violate the rights enshrined in the Second Amendment then it can violate the equal protection rights of same-sex couples with regard to marriage law or privacy rights with regard to abortion.
No right is absolute, including Second Amendment rights.
The question then becomes: how is this pending legislation potentially un-Constitutional?
