Homicide is a health issue both because it contributes significantly to mor
tality, particularly among young men, and because of the association betwee
n having a mental disorder and an increased probability of committing such
violence. Though the number of patients of mental health services who kill
is diminishingly small the public and political concern generated is enormo
us. Such concern usually manifests in the blaming of the services, individu
al clinicians, or both, The community expects mental health professionals t
o minimize the risks they face from mentally disordered people and, not unr
easonably, make little distinction between those rendered homicidal by psyc
hosis, chronic intoxication or personality. They also expect mental health
professionals to play a role in explaining the hows and the whys of such vi
olence, particularly when it manifests in its more outrageous variants such
as serial and mass murder. Those expectations are not unreasonable and a f
ailure to respond risks diminishing our profession's social significance. C
