Five years ago: Retired Ohio auto worker John Demjanjuk went on trial in Munich, Germany, accused of helping to kill 27,900 Jews as a Nazi death camp guard. (Demjanjuk was convicted in May 2011 of being an accessory to murder; he was sentenced to five years in prison, but was released while his conviction was under appeal; he died in March 2012 at age 91.) In Geneva, the Large Hadron Collider, the world's largest atom smasher, broke a world record for proton acceleration. Serena Williams was fined a record $82,500 for her tirade at a U.S. Open line judge. Tiger Woods withdrew from his own golf tournament, citing injuries from a car crash near his Florida home.
