"The Myth of Posse Comitatus" homelandsecurity.org

This is from the "Homeland Security Studies and Analysis Institute" website. The author is Major Craig T. Trebilcock, U.S. Army Reserve.

Imagine my surprise after all the fuss and now I learn it is a "myth". I sure am glad they got this straightened out

"The Posse Comitatus Act has traditionally been viewed as a major barrier to the use of U.S. military forces in planning for homeland defense. In fact, many in uniform believe that the act precludes the use of U.S. military assets in domestic security operations in any but the most extraordinary situations. As is often the case, reality bears little resemblance to the myth for homeland defense planners. Through a gradual erosion of the act’s prohibitions over the past 20 years, posse comitatus today is more of a procedural formality than an actual impediment to the use of U.S. military forces in homeland defense."

"Conclusion

Is the Posse Comitatus Act totally without meaning today? No, it remains a deterrent to prevent the unauthorized deployment of troops at the local level in response to what is purely a civilian law enforcement matter. Although no person has ever been successfully prosecuted under the act, it is available in criminal or administrative proceedings to punish a lower-level commander who uses military forces to pursue a common felon or to conduct sobriety checkpoints off of a federal military post. Officers have had their careers abruptly brought to a close by misusing federal military assets to support a purely civilian criminal matter.

But does the act present a major barrier at the National Command Authority level to use of military forces in the battle against terrorism? The numerous exceptions and policy shifts carried out over the past 20 years strongly indicate that it does not. Could anyone seriously suggest that it is appropriate to use the military to interdict drugs and illegal aliens but preclude the military from countering terrorist threats that employ weapons of mass destruction? For two decades the military has been increasingly used as an auxiliary to civilian law enforcement when the capabilities of the police have been exceeded. Under both the statutory and constitutional exceptions that have permitted the use of the military in law enforcement since 1980, the president has ample authority to employ the military in homeland defense against the threat of weapons of mass destruction in terrorist hands."
