Henceforth, the executive, by diktat, can claim emergency powers, declare martial law, suspend the Constitution on "national security" grounds, and deploy federal and/or National Guard troops on US streets to suppress whatever's called disorder - including lawful peaceful protests.
At issue is abolishing fundamental First Amendment freedoms without which all others are at risk. They include free expression, assembly, religion, and right to petition government for redress. No longer.
In 2009, Obama assured military commission continuity by signing the FY 2010 Defense Authorization Act. Its hidden Section 1031 contained the 2009 Military Commissions Act (MCA). The phrase "unprivileged enemy belligerent" replaced "unlawful enemy combatant."
Language changed but not intent or lawlessness. Obama exceeds Bush extremism. Guantanamo and other torture prisons remain open. US citizens are treated as lawlessly as foreign nationals. Ahead things got worse.
On December 31, he signed the FY 2012 National Defense Authorization Act (NDAA). It gives presidents unchecked power to order military force arrests and indefinite detentions of US citizens, based solely on uncorroborated accusations of terrorist group associations.
Constitutional, statute and international law protections don't apply. America's military may snatch and grab anyone, throw them in torture prisons, and hold them indefinitely without charge or trial, based solely on suspicions, spurious allegations or none at all.
Earlier by Executive Order, Obama authorized indefinite detentions of anyone designated national security threats. Specifically intended for Guantanamo detainees, it's now for everyone, including US citizens at home or abroad.
Moreover, CIA operatives and Special Forces death squads got presidential authorization to kill targeted US citizens abroad. As a result, they can be hunted down and murdered in cold blood for any reason or none at all.
