Statistics are misleading: Cops here, along with the Coroner, determine cause of death (i.e. Accident, Homicide, Suicide, etc)
In places like Britain, there is no official cause of homicide unless a conviction of murder or manslaughter is made in a case regarding the death. So unsolved crimes are not homicides. Nor are cases where the perp was not convicted by a court of law. . .
Thanks for the info!
