Random facts about Martial Law (i Wikipedia it, and did NO educational research on it.) I myself don't fully understand this concept, and im still learning on it. Maybe this might help others too. Here Goes: "The martial law concept in the U.S. is closely tied with the right of habeas corpus, which is in essence the right to a hearing on lawful imprisonment, or more broadly, the supervision of law enforcement by the judiciary. The ability to suspend habeas corpus is often equated with martial law. Article 1, Section 9 of the U.S. Constitution states, "The privilege of the Writ of Habeas Corpus shall not be suspended, unless when in Cases of Rebellion or Invasion, the public Safety may require it."

In United States law, martial law is limited by several court decisions that were handed down between the American Civil War and World War II. In 1878, Congress passed the Posse Comitatus Act, which forbids military involvement in domestic law enforcement without congressional approval. The Military Commissions Act of 2006 possibly rescinds these limits by suspending habeas corpus, but the law is not clear on whether it applies to U.S. Citizens. Since, USNORTHCOM [5] has increased its direct involvement with civilian administration"
