One thing I noticed during this "photo-op" of Mary: as she was pointing out the "pathetic" one lonely crane moving dirt to fix the levee, did you all notice that the water sheen indicated that the water was LEAVING the city back into the canal and to the lake. The Corps of Engineers said they are deliberately leaving some levees open because the lake is now lower than the level in the city. Keeping some of the breaks open is acting as a DRAIN. This is what she starting to "cry" about with complete mis-understanding of what the scene meant.
She's just plain stupid.
