Indianapolis 465 loop accident

I don't understand how 2 courts of law can give 2 totally different sentences for essentially the same accident.
This accident:
Woman sentenced to 51 years to life in prison for DUI crash that killed 3 Las Vegas teens in Huntington Beach

29 year old woman, drunk out of her mind, going down a street at 80 miles an hour, plows into the back of a car waiting at a traffic light. 3 teenagers inside burned to death, the other is permanently injured.
She gets 51 years in prison, eligible for parole in 30.

This accident in Indianapolis is a 57 year old man, taking all sorts of medications that should have made him ineligible for a CDL(except he lied to his employer and doctor) going 65 miles an hour, plows into a line of vehicles stopped in a construction zone. The first car he hits bursts into flames, the mother and twin 18 month old children burn to death, and injures at least a dozen other people.
He gets a plea bargain, 3-9 years in a mental hospital, when he will be eligible for release less than 2 years from now.

It is just wrong.

 

I agree. There are plenty of examples of truckers being blamed for stuff that isn't their fault, but this isn't one of them.
