If Bush had just "shaken the tree" more everything would have been fine. After all, that's how the Clinton administration caught the millennium bomber, right?
Not really. The alert never reached the customs agents. The arresting agent thought that the suspect was too nervous and had him open his trunk. She first assumed that the bags of white powder were drugs. It was only later that they looked closer and realized that it was explosive.
This story does not mention it but a customs agent shook bottle that later turned out to be filled with nitroglycerine.
