In a country which used to have the biggest Communist Party in Western Europe, May Day is an important festivity.
This year, however, it was darker than usual, with protesters clashing with the police in Turin, the traditional industrial heartland of Italy.
After years of good relations with the public, the Italian police is once again under attack after too many suspicions deaths of people under arrest. It was unusually attacked by political parties and its own Chief, Prefect Alessandro Pansa, after a riot police officer was photographed while kicking a female protester on the ground and a law enforcement personnel congress applauded a group of officers convicted for the manslaughter of a young boy during an arrest.
Some MPs are pressing for a law or regulation compelling riot police officers to wear an identification code on their helmets.
