A protester touches the shield of a riot policeman during a demonstration in front of the Greek Parliament building in Athens December 13, 2008. Riots since the Dec. 6 shooting of 15-year-old Alexandros Grigoropoulos have destroyed hundreds of shops, banks and cars, rattled the conservative government and shaken investor confidence in the 240 billion euro economy ($315 billion) as the global crisis bites.
