i think Blanko was politically chicken (as a white person) to bring the NG and their guns into her city of black persons. Fearing she'd be blamed for bullying them. Not expecting of course that the situation would go from bad ("oh let them steal food") to worse (OMG they've got the police under seige). A purely selfish political decision imo. Not caring at all for "her people".
I think there's definitely some of that involved.
One of the reasons that there will never be a definitive accounting for all this is that virtually the entire city government of NO is black, and therefore has to be handled with kid gloves. Sad, because of course the majority of those they failed were also black.
At first I was hoping that this obvious failure might prompt black "leaders" to forget their obsession with race and simply call for law and order and efficiency in NO, but obviously, they're in full "blame the man" mode now and will never look at the reality of the situation and how it could be fixed.
They should also be firmly repudiating the thugs that took over the city and making it clear that most of the black people of NO behaved themselves well and that the thugs are not representative. Instead they're rationalizing and excusing the thugs' behavior.
It would be really nice if some of these "black leaders" were really concerned about black people.
