Re: "And if the previous poster is correct, where the government can only look into foreigners library records, then I see no problem." Actually, most of the posters are incorrect and only reference one of the two sections of 50 CFR 1801, that being 50 CFR 1801(b)(1). The code clearly states that the act can be used to gather intelligence on a united states person as long as the investigation is not being conducted “solely upon the basis of activities protected by the first amendment to the Constitution of the United States”.

Can a United States Person be considered a ''Agent of a foreign power'', Yes.

I refer you to 50 CFR 1801(b)(2)
(2)
any person who -
(A)
knowingly engages in clandestine intelligence gathering activities for or on behalf of a foreign power, which activities involve or may involve a violation of the criminal statutes of the United States;
(B)
pursuant to the direction of an intelligence service or network of a foreign power, knowingly engages in any other clandestine intelligence activities for or on behalf of such foreign power, which activities involve or are about to involve a violation of the criminal statutes of the United States;
(C)
knowingly engages in sabotage or international terrorism, or activities that are in preparation therefor, for or on behalf of a foreign power;
(D)
knowingly enters the United States under a false or fraudulent identity for or on behalf of a foreign power or, while in the United States, knowingly assumes a false or fraudulent identity for or on behalf of a foreign power; or
(E)
knowingly aids or abets any person in the conduct of activities described in subparagraph (A), (B), or (C) or knowingly conspires with any person to engage in activities described in subparagraph (A), (B), or (C).

Thanks, your post was very informative. It is not what I had heard previous here at FR and elsewhere. However, it is logical that any U.S. citizen, including those whose parents are of Middle Eastern descent but born in the U.S., suspected of helping terrorists should be included. Then perhaps we might have used the Patriot Act to catch John Mohammed (sniper) and the miltary person who tried to frag his fellow soldiers waiting in Kuwait to enter Iraq. Perhaps we could have caught these U.S. citizens earlier before they killed fellow Americans.

This post actually makes me feel MUCH better that the Patriot Act includes these items.
