Bingo.
I will bet that the cops are going over the personal life and record of everyone anywhere near the set, from the janitor that cleans the rest room right up to Baldwin.
Why???
Because Baldwin is notorious, world famous for being an a**hole. He has abused so many people he has become famous for it.
There are people who brood over their mistreatment, whether real or imagined, for years and on one day try to get even.
Those are the people who mail bombs. wire the family car to explode, machine gun a car or house trailer even though it is occupied by women and children....
So suppose there was one such person on the crew. He knows the script requires Baldwin to point the gun directly at the camera and fire. He cares not who is behind the camera as long as Baldwin rots in jail, ruined, he will have paid him back.
Outlandish? Maybe, but remember people have burned down apartments to get revenge on one resident.
I am not saying this is what happened. I am saying that the cops are checking all kinds of stuff and we might get a surprise.
First they will want to know how long the guns were left on the tray and who was where during that time, and they will go back down the timeline to find out how they got on the tray...that chain of custody thing.
But bottom line...unless she put the live ammo in the gun, she is not a criminal. Maybe negligent under civil law, maybe not depending on what the investigation turns up.
But Baldwin is dead meat. If there is any justice in that jurisdiction, he will be tried in criminal court and sued in civil court.
Good points. Indeed, Alec Baldwin is internationally known for being a D**khead. Hence, you have legions of people to consider, each with a private motive to destroy his career and take his freedom of movement away.
