First Question: Is It The Good Kind of Sloughing?

Why wouldn't you want to trust your life to the Army Corps of Engineers when it takes this approach to its possible errors? If the story has the chronology right, the Corps knew of "sloughing" or erosion of part of the wall of the 17th St. Canal a year and a half ago, but didn't notify the local levee district, nor did it take remedial action. Now that the district has discovered the increasing erosion, the Corps will undertake tests. Of course, it's the middle of hurricane season, so the time frame for that testing of this crucial part of the flood-prevention system -- the other side of the canal from the floodwall that failed following Katrina -- will be...."soon."
