As to evacuations...
Let's avoid either-or, simplistic thinking and policy analysis!
The choice wasn't between doing an unplanned, uncoordinated mess of a mass evacuation a la Rita and doing nothing! Instead, as several leading emergency planners have noted, the city and state should have ordered targeted, limited, but
mandatory evacuations from the
worst flood plain, flood-prone areas. That would have gotten more people out of harm's way early -- without massive tie-ups -- and relieved some of the current burden on the search-and-rescue teams.
Our hearts go out to the people of the area. It's devastating. Like Katrina, though, much of it could have been avoided with smarter public policy, aggressive anti-global warming actions, updated building codes, and controlled development. Unchecked building in flood plains -- and paving over land that could have absorbed water -- were a recipe for disaster. We are angered by the lack of effective regulation and insurance requirements. We feel for those whose homes were flooded and now realize that they should have gotten flood insurance. Regardless of one's take on that, though, the stories of devastation are still gut-wrenching.
