I listened to an interview with the Mayor of N.O. last night, and he said that some of the refugee's had tried to leave the city via the only way out, which was north, and when they approached one of the town's or cities enroute, they were stopped by heavily armed police with dogs, and told that due to previous looting, they were not going to allow the victims to travel any further and to go back to where they came from.
Those town leaders need to be found, a case built against them, charges filled, and prosecuted to the fulliest extent of the law.
Granted, there are reports here in Houston, that a few of the refugee's are getting drunk, and causing problems, but we sure as hell aren't going to kick all of them out!
At most, there may be a curfew placed in effect, but that's still being checked for legalities.
