Milestones

Ten years ago: A jury in Northampton, Mass., found Amy Carter, Abbie Hoffman and 13 other protesters innocent of charges stemming from a demonstration against CIA recruiters at the University of Massachusetts.

Five years ago: Countries barred Libyan jets from their airspace and ordered diplomats to go home because of Libya’s refusal to turn over suspects in the bombing of Pan Am Flight 103. Hotel magnate Leona Helmsley began serving a prison sentence for tax evasion (she was released from prison after 18 months).

One year ago: President Clinton began a weeklong round-the-world trip, heading for a three-day visit to Japan after a brief stopover in Cheju, South Korea.
