By your definition, all accidental death is due to manslaughter. There's always another level of safety that can be built into a system, but at some point we have to say "good enough". That isn't to say we shouldn't strive to improve something, but death by school bus rollover is among the lowest causes of death in children.
The statistics don't properly flavor the loss experience of parents and family survivors whom will have to go on without the deceased.
The four-foot-high floor of the bus necessarily raises the center-of-gravity,making them ripe for rollover.Greyhound and charter buses as well.I'd like to see a side-by-side comparisons from the National Transportation Research Center.
I do believe the USDOT,NTSA,Bluebird and the other bus-makers, and purchasing departments are all guilty of manslaughter when I see this.
Peter Principle all-around.
