to me murder is murder its that simple, manslaughter is when there was NO intent to kill, of that i'm near sure, wheres blazey when ya need her?
i do think there is differant types/degrees as the yanks call it, so there must be different tariffs, killing n abusive partner should not come under the same banner as premeditated or killing fer killings sake, i agree with eric,each one should be looked at individually, and judged on that basis. thats my 2 pennorth.
