I don't know, but I wonder if it was also the same people who turned away the buses that arrived from other cities to evacuate people from the Superdome.
Well, the LANG is under the control of the Governor (still) so I guess there is only one place the order to abandon the Superrdome could have originated. I cannot confirm that such an order was given, nor even that they ever left. But we know that they were there before and during the hurricane, and it's hard to imagine the other stories of crime in the Superdome could have occured had the Guard remained. Or am I missing something?
