Italian Carabinieri pose in front of St. Peter's Basilica as a Carabinieri helicopter flies overhead, in Rome November 12, 2014. In Italy, police and the paramilitary Carabinieri follow the same guidelines, which say that the use of weapons is allowed only in the line of duty, when it is an “unavoidable necessity to overcome resistance, stop violence, or prevent a (serious) crime”, and that the response must be proportionate to the situation.
