I assume the GP is referring to the extreme side of a gradient that exists between 'random murder on the streets due to indiscriminate gunfire' and 'man forgets emergency brake on hill causing pedestrian to get hit (and die) as it rolls away' In the United States (no idea about any other country) there are multiple different crimes that equate to "your actions caused someone to die" such as homicide, manslaughter, involuntary manslaughter, vehicular manslaughter, etc. that all have their own conditions that must be fulfilled, some of which are based on the circumstances of the crime itself.
