Dozens of heavily armed cops guarded the opening this week of the trial of 19 alleged terrorists from Greeces notorious November 17 militant group. The Marxist group has claimed responsibility for more than 100 bombings and robberies and 23 murders over nearly 30 years. It first struck in 1975, killing Richard Welch, the CIA station chief in Athens, to express disapproval of U.S. support for the military junta that then ruled Greece. Later, November 17 adopted anti-globalization as its pet cause, bombing McDonalds restaurants and killing businessmen. Athens Mayor Dora Bakoyianni, whose late husband was one of the groups victims, will watch the proceedings, which are expected to last for months.
