Crime in Greece is combated by the Greek Police and other agencies. For much of the 20th century, the security forces were criticized for spending their time chasing people with left-wing political views, instead of focusing on actual crime. The crime rate in Greece has historically been amongst the lowest in Western Europe, and continues to be. The Greek Police also had several victories, breaking up mafia organizations, arresting the 17 November terrorist group, and successfully organizing security for the 2004 Olympic Games.
