In a 2006 interview, you gave the country a D+ grade when it comes to the current state of port and cargo security. And that D+ was up from an F a few years prior. Where do we stand now in 2008? We are moving probably to a C-minus. There are essentially three challenges in the area of port security and cargo security. The first is that potentially our ports can be used as a conduit to bring destructive things into country, such as a dirty bomb, a radiological device, or, in a worst case scenario, a nuclear bomb. So the first set of challenges is to figure out how do I find the needle in haystack in the tremendous volume of cargo and in a complex environment like our ports if someone wanted to smuggle something in.
