Its a damned if you do, damned if you don't situation.
You don't evacuate, Gustsav slam NO, and its back to "George Bush hates black people". Everyone loses.
You evacuate the city b/c the weather guessers say that Gustav is going to schwack NO, but instead, it doesn't. Now, you have people pissed off because you told them to leave.. even though they knew what could happen if they didn't.
Seem that the only way the gov't could win this one was to evacuate and then have NO get schwacked. But wait, if the levees didn't hold, isn't that the gov't fault too?
People don't realize that Pres. Bush and the rest of the federal gov't and state gov't didn't decide to build a city below sea level in the middle of hurricane alley.
