The evidence that we the people, are at risk of being placed under martial law, and losing all of our rights as guaranteed by the Constitution is overwhelming.
On October 17, 2006, President Bush signed into law, the John Warner Defense Authorization Act. The law allows the President to declare a "public emergency" at his own discretion, and place federal troops anywhere throughout the United States. Under this law, the President also now has the authority to federalize National Guard troops without the consent of Governors, in order to restore "public order." The President can now deploy federal troops to U.S. cities, at will, which eliminates the 1878 Posse Comitatus Act.
In short, President Obama can now declare Martial Law anytime he sees fit to do so.
