In the last years I visited public and private shooting ranges and houses of gun enthusiasts. I attended conventions, historical re-enactments and collective events in various regions around Italy. I searched socially accepted dynamics, I wanted to understand what conditioned and influenced individuals to sign the first contact for a gun. I was allured to the desire of understanding the mysterious attraction and repulsion that firearms generate in the collective imagery. In the military jargon, “friendly fire” designs the situation in which soldiers fall under the fire of their own fellows. In most cases it explores an error of identification: friends exchanged for enemies. I tried to experiment the inverse.
