Suicide by police: a proposed typology of law enforcement officer-assisted suicide

A typology of suicide by police was created by separating 143 such incidents from a database of 174 police shooting incidents. The 143 incidents were found to consist of three main categories: Direct Confrontations, in which suicidal subjects instigated attacks on police, Disturbed Interventions, in which potentially suicidal subjects took advantage of police intervention, and Criminal Interventions, in which subjects preferred death to submission. These three categories were then subdivided into nine types. Two judges obtained a reliability coefficient of 0.87 for distinguishing suicide by cop, and 0.58 for placement into the nine types. Meaningful distinctions among the types were found on three variables: subject age, real danger, and lethality.
