How Prepared Are We For Disasters?

An infrastructure expert says that though Irene wasn't as bad as predicted, he still saw some of the same mistakes that were made during Hurricane Katrina, which happened six years ago Monday.

Thomas O'Rourke, Cornell University engineering professor, says that mega-disasters are the "new normal" and not enough critical thinking is taking place ahead of time to decide what top infrastructure priorities are before what he calls "low probability high consequence events" like big storms.
