I don't see how any rational person could see any difference between dying in an accident and being murdered in a random, untargeted act. Is it dishonorable or something? Would they be heartbroken by this terrorist cell show of rudeness?

Now, if I were an embassador, or judge, or some big fish, I could understand that this intent would make an attack more probable. The vast majority of people, however, will never have the luxury of a powerful enough enemy mailing a fundamentalist hit squad to their homes. We, fortunately, are the tourist-class fliers of global terrorism, lacking any kind of personal attention.
