Criminal vs Civil liability are 2 different things.
Proving Baldwin, as an actor handling a prop gun at the direction of his boss pulled the trigger, is a hard sell for criminal charges for the death, at least not any serious charges.
I never expected him to face serious criminal charges, even if this happened in the reddest of red districts.
He was never going to face manslaughter or murder charges.
Civil court however, he almost certainly will be found to have some culpability, if the victims families sue.

Looks like involuntary manslaughter to me.
