Criminal negligence. Or depraved indifference. Either of which is what Baldwin should have been charged with, rather than manslaughter.
Movie sets have nonfunctional dummy bullets that are basically indistinguishable from live ammo. Most prop guns are REAL GUNS because they fire blanks, which are essentially every functional part of a “bullet” except the bullet itself. Every single one of these items is meticulously prepared, checked, and certified by the armorer to ensure their safe usage.
Bringing live ammo into that environment, using prop guns for target practice between filming, that’s not just stupid and negligent, that’s “keeping your drain cleaner in a soda bottle in the fridge” level stupid. It’s “leaving an open box of razor blades next to the Chuck E Cheese ball pit” level stupid. Gutierrez needs to never be allowed access to firearms again.
And Baldwin needs to answer for his role as her boss, and the one ultimately responsible for her actions on set. He didn’t commit manslaughter, but he should have faced charges for his mismanagement endangering everyone on set.
