Oklahoma:
A motor vehicle operator who unintentionally causes injury or death to an individual shall not be criminally or civilly liable for the injury or death, if:
1. The injury or death of the individual occurred while the motor vehicle operator was fleeing from a riot, as defined in Section 1311 of Title 21 of the Oklahoma Statutes, under a reasonable belief that fleeing was necessary to protect the motor vehicle operator from serious injury or death; and
2. The motor vehicle operator exercised due care at the time of the death or injury.

If you are trying to flee for your (perceived?) safety during a "riot", then it seems to be treated as a form of self defence (?).

I don't live in a world where killing 4 students simply for standing around while a protest was going on to be just, even factoring in property damage, but you do you
It's possible to describe/explain something without condoning it.
> Justice: The world may be a difficult place to live, but it is basically just; people usually get what they deserve. The difficulties in one's life serve as a test to sort the deserving from the undeserving.
