In some instances people were literally rounded up and placed in jail and prison cells. A Pakistani man died while jailed from a heart attack. He was refused most of the rights afforded citizens even then. Then there is Gitmo, but, that is a military installation and not a civilian prison. It would seem as though if Congress has its way the facility will remain open and include citizens of the USA.
The entire expansion of the President's powers is unnecessary because Marshall Law can be invoked to limit the rights of everyone. I am sure President Obama included or plans to include a signing statement, however, it seems like a redundant law, unnecessary and dangerous. It is these occasional brushes with citizen's rights that bring a great deal of skepticism as to what the heck is going on with the military and the elected officials of the Congress.
I am sure this provision will end up in a lawsuit nothing short of when the ink dries on the paper. The entire concept should have been addressed separately and without the appearance of sneaking through on National Defense Authorization Act of 2012.
