Posse Comitatus Act of 1878 (s) (noun) (no pl)

The name Posse Comitatus means, “the Power of the County”, bringing to mind colorful images of the old west county sheriff swearing in a posse to pursue fleeing criminals.

The Act was born out of the extensive use of federal troops for law enforcement in the South following the Civil War. Congress, recognizing that the long-term use of the Army to enforce civilian laws posed a potential danger to the military’s subordination to civilian control, passed the Act.

The 1878 Posse Comitatus Act made it a crime for anyone to use the Army to enforce federal, state, or local civil laws.

The prohibitions of the Act are directed at preventing the military from becoming a national police force or Guardia Civil. Accordingly, the Act prohibits anyone from using the military to “execute the laws". Execution of the laws includes the arrest or detention of criminal suspects, search and seizure activities, restriction of civilian movement through the use of blockades or checkpoints, gathering of evidence, and certain uses of military personnel as undercover narcotics officers.

In essence, the closer the role of the military personnel comes to that of a police officer on the beat, the greater the likelihood that the Act is being violated.

Military Involvement During National Emergencies

The frequency with which the military has become involved in civilian law matters has varied throughout our history, typically reaching high points during times of national emergency. The difference in the 1990’s; however, has been to increase the routine use of the military in domestic law enforcement activities during a period of relative national calm and security.

Statutes and regulations enacted in the past decade permit the use of military personnel in drug interdiction, and immigration enforcement.

Although such involvement is supposed to be “indirect” under those statutes, the reality is that armed active duty military personnel are carrying out an enforcement activity that brings them into direct contact with criminal suspects.

The fact is that the political interest in stopping drug and alien smuggling is currently greater than the concern as to whether the military is being injected into a traditional civilian law enforcement role contrary to the principles upon which the Posse Comitatus Act was founded.

The military possesses unique training and equipment advantages in this arena that cannot be duplicated by civilian law enforcement. The fact that the National Guard is not subject to the Posse Comitatus Act while in its state status also provides a great deal of flexibility to planners for homeland defense.

National Guard Troops May Be Employed in Law Enforcement

National Guard troops may be actively employed in law enforcement activities in addition to their military specialty. While to the untrained eye the distinction between a BDU (Battle Dress Uniform) clad Army Reservist and a BDU clad National Guardsman may be nonexistent, the legal distinction between them is significant.

During a natural disaster Army reservists or Guardsman may both provide logistical aid such as water purification, medical assistance, and communications; however, due to the Posse Comitatus Act, it is only the Guardsman in his/her State status that can take an active role in suppressing looting and in providing general security for an area that has lost effective law enforcement control.

Constitutional Authority of the President Allows Utilization of Military to Preserve Civilian Laws

By virtue of the several statutory exceptions to the Posse Comitatus Act in the past decade, coupled with the general Constitutional authority of the President to preserve order, there are few areas of domestic law enforcement activity where the military is precluded from participating in times of national emergency or disaster.

While the Posse Comitatus Act still serves a valuable function in deterring a lower level commander or politician from engaging in unauthorized “police” activity using military forces, the Act today provides little hindrance to the National Command Authority in executing civilian laws in times of emergency through military personnel.

Through proper, legal declarations of Presidential emergency authority and/or through the use of National Guard assets in state status, it is increasingly likely that the military will play a significant enforcement role in response to domestic terrorism and other disasters for the foreseeable future.
