Are you aware of the fact that 8 years later, the US is still in a state of emergency?
On September 10th, President Obama reinstituted the national State of Emergency first declared by George W. Bush on September 14, 2001 by placing the following language in the Federal Register.
The terrorist threat that led to the declaration on September 14, 2001, of a national emergency continues. For this reason, I have determined that it is necessary to continue in effect after September 14, 2009, the national emergency with respect to the terrorist threat.
As Dr. Harold C. Relyea, a specialist in national government with the Congressional Research Service (CRS) of the Library of Congress, has written, “when the President formally declares a national emergency, he may seize property, organize and control the means of production, seize commodities, assign military forces abroad, institute martial law, seize and control all transportation and communication, regulate the operation of private enterprise, restrict travel, and, in a variety of ways, control the lives of United States citizens.”
