The only justice here would be changing the road design, driver licensing, and training to prevent this from happening in the future.

The NTSB concluded that driver fatigue was to blame for the deadly collision

Fatigue is a known threat to safety. Fatigue is not discussed during driver training. An understanding of the dangers of fatigue is not tested during driver licensing. Roads can be designed to prevent known human weaknesses like distraction and fatigue from killing people. All of these things can be fixed. These deaths were preventable.

There is no justice in this case. Justice is not punitive.
