Also, past behaviors factor in to how we view/deem accidental vs neglectful.
Lady across the street has little children....one too young to potty train...and they are ALWAYS in the street, been brought home stark naked by police from around the block, constantly with no supervision what so ever. I mean they are in the street, around the corner, with NO ADULT EVEN OUTSIDE!
I know people in this neighborhood would look at it as neglect ON HER PART if one of her children were hit by a car. Someone else's child gets hit the same exact scenario? Ya...probably viewed an accident.
True, dead is dead but I agree with RTH about intent and IMO reputation/past behaviors is also a big factor.
