I think the feds are going to do something fast to end the lawlessness in New Orleans. Shooting LE and rescuers just ain't gonna fly. Thusands are still trapped on roof tops and in buildings, criminals halting relief operations must be dealt with and fast, night fall is comming. I would be surprised if the military didn't sent in an advance force to give the criminals something to think about.
