Without going back and re-reading complete thread, didn't someone earlier in the thread compare this to a car accident. If so, I fail to see the comparison.
If I take my car out in the country where there's little population, knowing it has no brakes, or the gas pedal is sticking to the floor and I run over someone killing them do to the brakes or pedal failing, is that an accident or involuntary manslaughter/negligent homicide?
If I'm carrying my hunting weapon via a sling on my shoulder, I fall, my weapon discharges, shooting someone that's an accident.
Same scenario as above but I know my safety is broke, I couldn't call that an accident.
As sad as it is for everyone concerned , I just don't see this ending in the shooting ' accident' files without further stipulations.
