"When Katrina hit, some people wanted to know why the feds didn't send in troops to keep order."
The KKK/Blackwater people may have wondered that -- what the rest of us want to know is why the feds didn't send in *food, water and meds*. Also why the feds *prevented* private parties and other oganizations, including some military, from sending in food water and meds.
No amount of "but first -- send the marines" is of any help there at all.
