I found the picture on the Associated Press website. Here's the caption:
Rabbi Meir Kahane, right, founder of the militant Jewish Defense League, said that he would try to establish an Israeli settlement in the largest Arab city on the West Bank of the Jordan River. At left is Victor Vancier, executive director of the Committee Against Israeli Retreat (CAIR), joining Rabbi Kahane for a New York news conference, June 8, 1977. (AP Photo/Marty Lederhandler)
