The Court used Section 1 of the Fourteen Amendment to justify their argument, which reads:
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside. No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
By using the Constitution in such a manner, the Court argues that the Due Process Clause extends “certain personal choices central to individual dignity and autonomy” accepted in a majority of states across the state lines of a handful of states that still banned the practice.
The vast majority of states are “shall issue” on the matter of issuing concealed carry permits, and enjoy reciprocity with a large number of other states.
My North Carolina concealed carry permit, for example, was recognized yesterday as being valid in 36 states, which just so happened to be the number of states in which gay marriage was legal yesterday. But 14 states did not recognize my concealed carry permit yesterday.
Today they must.
