a 60 Minutes report brought together 12 men named Robert Johnson, all of whom had experienced problems in airports with being pulled aside and interrogated. The report suggested that the individual whose name was intended to be on the list was most likely the Robert Johnson who had been convicted of plotting to bomb a movie theater and a Hindu temple in Toronto. In August 2004, Senator Ted Kennedy told a Senate Judiciary Committee discussing the No Fly List that he had appeared on the list and had been repeatedly delayed at airports. He said it had taken him three weeks of appeals directly to Homeland Security Secretary Tom Ridge to have him removed from the list. Kennedy said he was eventually told that the name "T Kennedy" was added to the list because it was once used as an alias of a suspected terrorist. There are an estimated American men whose legal names correspond to "T Kennedy". (Senator Kennedy, whose first name was Edward and for whom "Ted" was only a nickname, would not have been one of them.) Recognizing that as a U.S. Senator he was in a privileged position of being able to contact Ridge, Kennedy said of "ordinary citizens": "How are they going to be able to get to be treated fairly and not have their rights abused?" Former mayor of New York City Rudy Giuliani pointed to this incident as an example of the necessity to "rethink aviation security" in an essay on homeland security published while he was seeking the Republican nomination for the 2008 presidential election. The late U.S. Representative, former Freedom Rider, and former Chairman of Student Nonviolent Coordinating Committee, John Lewis, was stopped many times in his life. Canadian journalist Patrick Martin has been frequently interrogated while traveling, because of a suspicious individual, believed to be a former Provisional Irish Republican Army bombmaker, with the same name. Walter F.

The airline employee asked, "Have you been in any peace marches? We ban a lot of people from flying because of that." Replied Murphy, "I explained that I had not so marched but had, in September 2006, given a lecture at Princeton, televised and put on
