Several posters have actively been encouraging the President to break the law. At least, I think they are. But I believe it is unintentional. So here's a small excerpt and explanation of the laws that may apply to Katrina. "one of the express missions of the Guard is to preserve the laws of the state during times of emergency when regular law enforcement assets prove inadequate. It is only when federalized pursuant to an exercise of presidential authority that the Guard becomes subject to the limitations of the Posse Comitatus Act. Congress has also approved the use of the military in civilian law enforcement through the Civil Disturbance Statutes: 10 U.S.C., sections 331–334. These provisions permit the president to use military personnel to enforce civilian laws where the state has requested assistance or is unable to protect civil rights and property. In case of civil disturbance, the president must first give an order for the offenders to disperse. If the order is not obeyed, the president may then authorize military forces to make arrests and restore order. The scope of the Civil Disturbance Statutes is sufficiently broad to encompass civil disturbance resulting from terrorist or other criminal activity. It was these provisions that were relied upon to restore order using active-duty Army personnel following the Los Angeles “race riots” of the early 1990s. Federal military personnel may also be used pursuant to the Stafford Act, 42 U.S.C., section 5121, in times of natural disaster upon request from a state governor. In such an instance, the Stafford Act permits the president to declare a major disaster and send in military forces on an emergency basis for up to ten days to preserve life and property. While the Stafford Act authority is still subject to the criteria of active versus passive, it represents a significant exception to the Posse Comitatus Act’s underlying principle that the military is not a domestic police force auxiliary." I apologize for having inadvertantly deleted my source on my notepad.
