I recently flew with my family from Tel Aviv to Boston via Rome. The day was full of long lines, bomb-sniffing dogs, the opening and searching of overfull suitcases and the struggles to close them up again. In Rome, every single person on our flight was patted down and searched. We must have shown our passports 20 times.Impromptu debates arose as people from all over the world waited in line together. Was it better to search for the explosive device, as the Americans do, or for the bomber, as the Israelis do? Do the airlines need better technology or better training in behavioral screening? Has the war on terror made us more safe or less?
