Trials

Television Critic David Bianculli previews this week's "American Playhouse" presentation on PBS titled "The Trial of Bernhard Goetz." Goetz was acquitted last year of assault charges stemming from his shooting of four black youths in a New York City subway car after, Goetz contended, the youths tried to rob him. The trial, which dominated the New York City press for several weeks, was known as "The Subway Vigilante" trial.
