Has the bill passed the House and the Senate?

If so, where in the bill is the section that you are currently referring to?

The contentious unlimited detention sections are 1031 and 1032 --

While 1032 seems to offer some questionable protection for U.S. citizens from unlimited military detention, by giving precedence, in at least some cases, to civilian law authorities, there is some question about the term "not required" as meaning "still an option",

Section 1031, paragraph (e), the Feinstein addition, which exempted American Citizens on American soil from military arrest and unlimited military detention, including the use of "enhanced interrogation techniques", without official charges or notification, or any other public acknowledgement or civil recourse -- that paragraph was eliminated in the "reconciliation version" of the bill which Obama finally signed on Dec. 15. Apparently it was Obama who insisted on its elimination, saying that no one should be exempt from the law.

These sections fall under military laws of war, and such measures as unlimited detention can remain in effect until "the end of hostilities" which, considering the nature of the "war on terror" would seem indefinite indeed.

People can be picked up and detained without evidence, the criteria being that the President OR the military suspects them of belligerent acts (not defined) or association with or supporting others who are suspected of engaging in belligerent acts against the U.S. or its coalition members.

Can of worms, eh?
