Compilation of articles on the following act :

http://en.wikipedia.org/wiki/National_Defense_Authorization_Act_for_Fiscal_Year_2012

the Act legislatively codifies[6] the President's authority to indefinitely detain terrorism suspects, including American citizens, without trial 

as defined in Title X, Subtitle D, SEC 1031(a-e) of the bill.[7] Because those who may be held indefinitely include U.S. citizens arrested on American soil, and because that detention may be by the military, the Act has received critical attention by theAmerican Civil Liberties Union (ACLU) and media sources.[8][9][10][11][12]

 throughout the country."

"One provision would authorize the military to indefinitely detain without charge people suspected of involvement with terrorism, including United States citizens apprehended on American soil. Due process would be a thing of the past."

Ambiguous but alarming new wording, which is tucked into the National Defense Authorization Act (NDAA) and was just passed by the Senate, is reminiscent of the “extraordinary measures” introduced by the Nazis after they took power in 1933.
...
In sum, the wording appears to create a parallel military justice system that, theoretically, we are all subject to. All that would be needed is an allegation by someone that we assisted someone who in some way assisted someone else in some way. An actual terrorist act would not be needed – and neither would a trial by one’s peers as guaranteed by the Constitution to determine actual “guilt.”
