Therefore, since the 2nd. Amendment protects the "right of the people to keep and bear ams", this then protects the "right" of the National Guard to keep and bear arms"? I don't think so. Government does not have rights. Individuals do. Government has powers. And duties. In this case, government is charged with protecting the rights of individuals, not diminishing those that exist, or assuming powers it does not have.
The right of The National Guard to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the Guard personnel or things to be seized.
