Contagious shooting

A contagious shooting is a sociological phenomenon observed in military and police personnel in which one person firing on a target can induce others to begin shooting. Often the subsequent shooters will not know why they are firing.^[1][2][3]

This is defined as "officers firing because others are doing so," or according to Professor Eugene J. O'Donnell of John Jay College, "cops shoot because other cops shoot."^[4] While commonly accepted in popular culture and police jargon, there has been yet no scientific evidence "to prove the existence of a contagious shooting dynamic," which O'Donnell said was a "debateable notion."^[4]

In classic cases involving contagious shooting, "a gun was shot before any officers fired," and thus "the officers involved began shooting because of fear or because of the sound of a colleague firing."^[4]

This phenomenon has also been observed in military First Person Shooter games^{[citation needed]}.

• New York Daily News; March 10, 1999; "A lawyer for one of four cops who shot Amadou Diallo hinted yesterday that a phenomenon known as "contagious shooting" — in which a cop's shot sparks a volley from other officers — may have caused his client to fire 16 shots...

Thomas Reppetto, head of the Citizens Crime Commission, said the term contagious shooting was used during 1960s riots when a cop would fire at what he thought was a sniper and other officers would follow."

New York Times; November 27, 2006; It is known in police parlance as "contagious shooting" gunfire that spreads among officers who believe that they, or their colleagues, are facing a threat. It spreads like germs, like laughter, or fear. An officer fires, so his colleagues do, too. The phenomenon appears to have happened last year, when eight officers fired 43 shots at an armed man in Queens, killing him. In July, three officers fired 26 shots at a pit bull that had bitten a chunk out of an officer’s leg in a Bronx apartment building. And there have been other episodes: in 1995, in the Bronx, officers fired 125 bullets during a bodega robbery, with one officer firing 45 rounds…
