The Constitution is a document, actually a contract of sorts, that delegates authority and power to the Federal government. It also places strict limits on the federal government of the United States. It empowers the Congress to act in certain specific areas. It empowers the Executive to execute those acts, and the Judicial to ajudicate disputes involving the federal government and to review acts of the Congress to be certain that they act within the limitations of the Constitution.
The Bill of Rights protects our rights by prohibiting the Congress and the Federal government (and in some cases the several states) from violating our rights. These amendments are limitations on the power of the federal government, not grants of rights to people. As they are limits on the federal government, they apply whenever the Congress and the executive acts. These limits generally apply no matter whether the actions are against United States citizens, or against foreign citizens living in the United States as guests on visas and "green cards."
As to your statement:
Doesn't he realize that the Bill of Rights and the Constitution clearly identifies who is covered by the words "WE THE PEOPLE OF THE UNITED STATES", and that not everyone on this soil is "OF THE UNITED STATES"?Note that the constitution starts "We the People" not "We the Citizens". It applies to all people (legally) in these United States, not just citizens.
Note that the constitution starts "We the People [OF THE UNITED STATES]". It is a contract between those who have granted the government certain authorities and that government. BTW, please advise as to when all governments will be Republican in form...and when we can start collecting taxes from them.
