Name the host city or the year. The boxing at this city's Olympics were probably the last great year for the U.S, though this was helped by a Cuban boycott. Among other things, a referee from New Zealand had to flee the country after coaches and officials from the host nation's rushed the ring and began punching and kicking the referee after a decision against one of their boxers. The losing boxer, embarrassed, then refused to leave the ring for over an hour in protest. Identify these games who later saw Roy Jones, Jr. lose the gold medal despite out hitting and out defending himself against a boxer from the host nation. Years later, it was determined that judges were bribed, but the IOC still refuses to overturn the mockery of a decision.
