This episode of The MacNeil/Lehrer NewsHour looks at the following stories. The first story reports on a prisoner exchange between Israel and and the Palestine Liberation Organization (PLO). Judy Woodruff follows with a report on Eden Pastora, aka Commander Zero, a socialist-turned-centrist making a plea for American assistance in turning Nicaragua a unified country. Then Charlayne Hunter-Gault delivers a story on how the American shoe industry is fending off foreign competition with new technologies, including computers for designing shoes. She also concludes the NewsHour by interviewing Karl Menninger, a psychiatrist who advocated for treating the mentally instead of punishing them.
