The Constitution applies to the federal government—not Americans, citizens, or "people."
The words of the Constitution tells the federal government what it is allowed to do, and in some places it explains how to do it.
The Bill of Rights tells the federal government what it is not allowed to do.
Get it right.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
