Back in 1992 the Pentagon’s Joint Chiefs of Staff held a "Strategy Essay Competition."
The winner was a National War College student paper entitled, "The Origins of the American Military Coup of 2012." Authored by Colonel Charles J. Dunlap, Jr. the paper is a well documented, "darkly imagined excursion into the future." The ostensibly fictional work is written from the perspective of an imprisoned senior military officer about to be executed for opposing the military takeover of America, a coup accomplished through "legal" means. The essay makes the point that the coup was "the outgrowth of trends visible as far back as 1992," including "the massive diversion of military forces to civilian uses," particularly law enforcement.

Dunlap cites what he considered a dangerous precedent, the 1981 Military Cooperation with Civilian Law Enforcement Agencies Act, an act that sanctioned US military engagement with law enforcement in domestic “support operations,” including “civil disturbance” operations. The act codified the lawful status and use of military “assets” in domestic police work.

Encroachment upon Basic Freedoms
Since that time the American people have been subject to a series of deeper and deeper encroachments upon our basic freedoms, increasingly extensive deployment of military operations on the home front, perpetrated by a corporate driven military mission creep that now claims the right and duty to arrest and detain us on the word of a Pentagon or White House operative. President Obama’s signing of the 2012 National Defense Authorization Act (NDAA) whose Section 1021 sanctions the military detention of American citizens without charge, essentially aims to put the last nail in the coffin of our Constitution, our teetering Republic and our most basic democratic traditions.
The statute contains a sweeping worldwide indefinite detention provision. While President Obama issued a signing statement saying he had “serious reservations” about the provisions, the statement only applies to how his administration (“you can trust me”) would use the authorities granted by the NDAA, and would not affect how the law is interpreted by subsequent administrations. The White House had threatened to veto an earlier version of the NDAA, but reversed course (of course) shortly before Congress voted on the final bill, which the President signed on the 31st of December 2011, a day that will go down in infamy.
