Hong Kong Last year, Congress congratulated itself for passing a law that purported to implement the recommendations of the 9/11 Commission. The act included a requirement that overseas ports scan 100 percent of containers shipped to the United States. Before applauding, let’s review a few facts:

• The 9/11 Commission never recommended 100 percent screening.

• There is no threat that justifies 100 percent screening. (Think about it. What self-respecting terrorist would let a smuggled nuclear weapon out of his positive control by packing it into a container? There are much more dependable ways to smuggle nuclear weapons, dirty bombs, or whatever into the U.S. And ports are just as easily attacked from land as from the sea.)

• Existing technology can’t possibly screen fast enough or accurately enough to meet the 100 percent requirement.

• The current system, the Container Security Initiative, which inspects “high risk” containers before they leave foreign ports for the U.S. works perfectly well — i.e., Congress “fixed” something that wasn’t broken.

Every official I’ve talked to here in Hong Kong agrees that inspecting every container is ridiculous proposal. I just wish they would tell Washington. And Washington should listen. After all, Hong Kong is the busiest container port in the world and one out of every five containers it ships out is headed to the United States. Here are three things Hong Kong’s port security pros ought to tell the amateurs in Washington:
