A well done post about Katrina, the victims, and the levees, at RealClearPolitics, which can be found here: The post points out what went right, and how it seems that the TV media especially has sloppily performed in what could have been a time to excel.
"Besides the large number of rescuers, there was another key reason for the success of rescue efforts. The nature of the flooding differed from the scenarios that would have resulted in 10 to 25 thousand dead. Worst case models projected a storm surge that overtopped the levies by 10 feet, destroying them and creating an instant flood at or near the time a Cat 5 hurricane leveled 80 percent of the structures in the city and environs.
That only happened in parts of the city, eastern New Orleans. It is clear from video footage that even there much of the housing survived, at least insofar as it provided a few days of refuge from flood waters. The flooding elsewhere was extensive, but not always rapid--in many areas the rise was six inches to a foot per hour, easily evaded by a moderately fit adult or child.
Flooding didn't crest until Sept. 2, giving rescuers a five-day window in which to prioritize operations for the most desperate. Even then, few homes were overtopped and submerged."
Thank you Mr. Dolinar.
