"And if you will not answer why you want in my house=GO AWAY "

The U.S. is their home, they are citizens. They are being denied access to their own house to your your analogy.

"The safety of America is at stake. Ask as many questions as you want"

America was created by the Constitution, you do not protect something by destroying it.

Yes the constitution is what defines and mandates our laws

They were not even detained.

They were not denied theit constitutional rights

They refused to answer questions and if they invoked their "right not to answer any questions on the grounds that it may tend to incriminate me" was not anywhere in the article. And if it was I stand corrected.

I think the 800lb. gorilla on this thread is the fact that, if the U.S. feels this person (or these people) is/are a danger, then it should initiate revocation/deportation proceedings.

The U.S. is their home, they are citizens.

One is a 'naturalized' citizen. Having taken the oath required, he is bound by it:

Naturalization Oath of Allegiance to the United States of America
"I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state or sovereignty, of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the armed forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God."

If you ask the government to give you something tangible (like citizenship), they permanently maintain the right to take it back.

The other, supposedly a 'US citizen' by birth, really isn't unless he was born in Washington, D.C. or in a port, fort or arsenal.

"Every Person born within the limits of the United States, and subject to their jurisdiction, is by virtue of natural law and national law a citizen of the United States. This will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of ambassadors or foreign ministers accredited to the Government of the United States, but will include every other class of persons."
Senator Jacob Howard, co-author of the citizenship clause of the 14th Amendment, 1866.

I don't always like what the government does either, but that doesn't mean they don't have the legal right to do it anyway.
