This 2016 study examined "All fatalities resulting from use of lethal force by on-duty Law enforcement from 2009 to 2012 in all 17 U.S. states using National Violent Death Reporting System data."
Unlike the data the OP is based upon and most of what is posted in this thread, This data source does not rely solely upon reports created by the officers who killed the "suspects".
"NVDRS is a state-based surveillance system that links data on violent deaths (e.g., suicide, homicide, legal intervention) from death certificates; coroner/medical examiner reports; and LE reports in an incident-based, confidential data set. ...Data abstractors in each participating state review investigative findings from each data source and abstract information on incident circumstances and characteristics of victims and officers using standardized coding guidance. NVDRS also includes two narratives generated by the state abstractor containing a brief description of the incident based on information from the coroner/medical examiner and Law enformcement reports."
Major findings related to race:
"Blacks had 2.8 times the rate of deaths by law enforcement compared with whites"
Among those who died due to lethal force by law enforcement:
Blacks were 50% less likely to be armed.
Whites were 16% more likely to have been deemed "a threat to law enforcement.
"the percentage of “suicide by cop” cases was almost seven times higher for whites than blacks" (27% vs. 4% of deaths for each group).
"Suicide by cop" was determined using "Evidence from witness/Law enforcement accounts suggesting that victim was actively suicidal and engaged in life-threatening or criminal behavior directed at Law enforcement to elicit use of lethal force. Evidence of suicidal intent could include: suicidal behavior/threats during incident, suicide note, prior expression of intent/desire to be killed by LE reported by an informant, taunting/asking LE to kill them during the incident."
In sum, this is evidence that blacks are much more likely to be killed by cops, and yet when they are killed they are less likely than whites to be armed, a threat, or trying to use the encounter to commit suicide.
