Testimony is offered by U.S. Senators, representatives of the Justice and State Departments, and private attorneys and legal educators. The testimony considers U.S. legal authority to arrest and prosecute Arafat for his alleged complicity in the March 1973 murders in Khartoum, Sudan, of U.S. Ambassador Cleo Noel and Charge d'Affaires G. Curtis Moore. Also reviewed are the propriety of convening a special grand jury to investigate the pattern of PLO criminal and terrorism activity along with the status of existing laws which may be used against the PLO. Other issues addressed are the need for legislation to give the Justice Department stronger weapons against terrorism and to give terrorism victims means to attach PLO holdings in the United States. The subcommittee reviews the ease with which the members of the PLO and other terrorist groups are granted visas to enter the United States and the propriety and legality of the PLO's having an information office in Washington, D.C., and an observer mission to the United Nations. Newspaper and magazine articles as well as other relevant papers and materials are provided.
