Your government hates you and is trying to cover that up. Now, some are trying to say perhaps this is all a collosal mistake, and after all "The function of bureaucracy is to disguise the origin and nature of a mistake." Jon Carroll is great, and the rest of that column is great; but the destruction of New Orleans is not a mistake; it's intentional:
A person who has no drinkable water will die in three days. The survivors of Hurricane Katrina have been stranded twice that long—and still Brown doesn’t think it’s time to send in aid! With the authorities now threatening to evacuate the city, the only “natural time” he can possibly be waiting for is the point where no one who needed help is still alive in New Orleans. Brown has been actively prohibiting aid to the city. Under his direction, FEMA has repeatedly and unambiguously prevented aid of all kinds from getting into the city. [...]
If you are still truly desperate to keep Bush and his staff from being convicted on "with malice aforethought" circumstances, consider this line making the rounds, a combination of Clarke's Law and an old proverb:
Any sufficiently advanced incompetence is indistinguishable from malice.
Which is expanded on here:
It is not necessary to claim that the President of e.g. the USA is setting out to kill a maximum number of African Americans out of deliberate spite. It is sufficient to point out that if you take a job involving life and death, and go on doing it when you are clearly incompetent, then you are morally responsible anyway. There is a duty not to be crap at what you do.
There are thousands of reports (don't believe me? start with this, this, this, this, this, and this) telling how the Bush administration is preventing disaster relief. Prosecutors all over the country have plenty of language for this kind of behavior; the most generous of those is "willful negligence", but "murder" is much more appropriate.
