It now appears to be a done deal, President Obama will sign the 2012 National Defense Authorization Act (NDAA) which in all but name officially establishes martial law in the United States.
This tragedy directly results from the failure to properly repudiate the demagogic falsehood that the nation is "at war" with terrorism. So now even the homeland is legally a "battlefield" in the so-called "Global War on Terror", (that particular terminology having fallen from favor even as the logic of it became established as political dogma).
Of all the politicians aspiring to be elected, or re-elected, President only Rep. Ron Paul retains the belief that the Constitution, including the habeas corpus clause and the Bill of Rights, remains the supreme law of the land. Electing him President appears to be the last best hope of freedom loving Americans.
