CCW training stands for Concealed Carry Weapon(s). Typically this training is a requirement for obtaining your CCW Permit, which allows the state to license you to carry a concealed handgun. Some states do not require licensure to carry lawfully concealed handguns. These states are called Constitutional Carry states, as they follow the exact wording of the 2nd Amendment.
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
Second amendment, united states of america constitution
Up until 2008, the law of the land was heavily infringed upon. This was in part due to a devastatingly incorrect assesment of the 2A and the 14A. United States vs. Cruikshank(1876) https://supreme.justia.com/cases/federal/us/92/542/. This particular case was troublesome because it stated the constution did not reflect limitations on state governments, but only on congress and the federal government. Anyone with a general understanding of our laws understands this is not only false, but was punitive in nature due to the results of the aftermath of the Civil war, and the need for the north to punish and quell white supremacy. This constituted a false duality in statehood. The states and its citizens were not 100% subject to the consitutional law, but a duality of laws. This is problematic when they do not coincide with the bill of rights, the irony is not lost however, becase in the same breath… they overturned the convictions of the white democrats that killed three black republicans. The Majority opinion is as follows.
There is in our political system a government of each of the several States, and a Government of the United States. Each is distinct from the others, and has citizens of its own who owe it allegiance, and whose rights, within its jurisdiction, it must protect. The same person may be at the same time a citizen of the United States and a citizen of a State, but his rights of citizenship under one of those governments will be different from those he has under the other.
Chief Justice Morrison waite
The ruling said that all U.S. citizens are subject to two governments, their state government and the other the national government, and then defined the scope of each:
The Government of the United States, although it is, within the scope of its powers, supreme and beyond the States, can neither grant nor secure to its citizens rights or privileges which are not expressly or by implication placed under its jurisdiction. All that cannot be so granted or secured are left to the exclusive protection of the States
Chief Justice Morrison waite
The \dissenting minority opinion was from Justice Clifford. Justice Clifford agreed with the other Justices to rescind the indictments but for entirely different reasons: he opined that section five of the 14th Amendment invested the federal government with the power to legislate the actions of individuals who restrict the constitutional rights of others, but he found that the indictments were worded too vaguely to allow the defendants to prepare an effective defense.
Cruikshank has been cited for over a century by supporters of restrictive state and local gun control laws such as the Sullivan Act.
