I agree with you, but there are some tough questions to be answered nevertheless, including why, with our incredible engineering and technology skills, the levees weren't built to hold up. Surely someone, somewhere did a computer modeling study of exactly what the levess could withstand. I'm willing to bet that there is a person out there who repeatedly warned about such a dissaster who wasn't listened to.
Original specifications were to withstand a Cat 3 storm. That's what the ACOE built. Katrina was a strong Cat 4.
NO is run by liberal Democrats. I guess that answers that.
