No they DIDN'T. They talked about the possibility of the levees being TOPPED. To illustrate the difference: Imagine you are running water in your bathtub and the phone rings so you step out to answer the phone. When you return to the bathroom you find the water is starting to run over the edge of the tub onto the floor, so you turn off the water and perhaps you open the drain. Then the water is no longer running over the edge of the tub. This is an example of your tub being TOPPED. On the other hand, imagine that the side of your tub splits apart so that all the water pours out onto the floor. Now, even if you turn the water off, the water continues to pour out until the level is below the lowest point of the split or possibly until the tub is completely empty. This is an example of your tub being BREACHED. Now, when you went to answer the phone with the water still running, you should have anticipated the possibility that your tub would be topped if you talked on the phone too long. But there is absolutely no reason that you would have anticipated that your tub would split in two and be breached. See the difference? If you do, you are smarter than the average MSM reporter.
Well, except that when you moved in, there was an old footed tin tub in there and you replaced it with a modern one.
Then one winter, while you were on vacation, the pipes froze in your house and all the tile crumbled and the bathtub split in two. You put in a claim with your insurance company and they gave you a check for $20,000 to repair your bathtub.
You bought a hot tub for your outside deck, on sale for just $2 grand. You got some adobe mud and packed it in the crack in your bathroom tub and went to Las Vegas with the rest of the money.
When you left the tub filling while answering the phone, the mud washed out and breached. You had a flooded bathroom, hallway, bedroom, living room, house.
