blanco and nagin should be fired plain and simple
Fired? You're much to kind. I would have them arrested and charged with Depraved Indifference with Reckless Endangerment and 1,000 counts of Reckless Homicide and Dereliction of Sworn Duty with Intent to Commit Mayhem.
God as my witness, both Blanco and Nagin would be getting the needle in Federal Detention by the time I was through with them.
