Here is the definition from the source:
List of countries by intentional homicide rate per year per 100,000 inhabitants. The reliability of underlying national murder rate data may vary.[1] The legal definition of “intentional homicide” differs among countries. Intentional homicide may or may not include infanticide, assisted suicide or euthanasia.[2]
Any mention of lawful intentional homicide ( self defense, police etc? Gotta get to the real numbers of illegal homicide/crime etc. Otherwise, it is just vagueness manipulated for political purposes.
