Killing of a human being by another human being. The ARD program gathers data on homicides that occur during an arrest process regardless of whether the homicide was attributed to law enforcement personnel or a civilian. Homicides by law enforcement personnel were included in the ARD collection because they resulted from a direct use of force by law enforcement officers. However, not all homicides by law enforcement personnel involve shooting deaths. Other types of homicides by law enforcement officers included deaths attributed to asphyxia during restraint, injuries sustained during an altercation, and the use of technologies such as, chemical sprays and conducted energy devices.

Public Law 83-280 (commonly referred to as Public Law 280 or P.L. 280)
Establishes criminal justice responsibilities among American Indian tribes with tribal land, the states in which tribes are located, and the federal government. Public Law 280 is mandatory or optional for 204 tribes, about two-thirds of the total in the lower 48 states. In states where P.L. 280 does not apply, the federal government retains criminal jurisdiction for major crimes committed under the Indian Country Crimes Act (Title 18, United States Code, Section 1152), the Indian Country Major Crimes Act (Title 18, United States Code, Section 1153), and the Assimilative Crimes Act (Title 18, United States Code, Section 13).

Intentional killing of oneself. BJS recorded arrest-related deaths as suicides only if medical staff deemed the decedent deliberately took his or her life. The most common type of suicide reported to the ARD program included decedents engaging in armed standoffs with law enforcement prior to taking his or her life. Other suicides occurred while law enforcement officers were attempting to apprehend the deceased, who committed suicide to avoid being taken into custody. Drug and alcohol overdoses were not considered to be suicides unless there was evidence the overdose was intentional. Unintentional over use of alcohol or drugs for recreational purposes were coded as intoxication deaths. Deaths that were submitted as suicide by cop, were recorded in the ARD collection as homicides because the death was directly attributed to actions taken by law enforcement personnel.
