So far a couple of crew on set have said that the director and/or cinematographer wanted another take on the scene Baldwin was in. Baldwin got pissed off, pointed what he thought was a prop gun at them, uttered profanities and fired.
So far on separate threads I've seen two versions of the same story and given Baldwin's well known volatility, it's entirely possible it happened that way.
Baldwin is a total POS. Remember what he said to his own daughter years ago—called her a disgusting little pig—and assaulted a photographer too in NYC. If this is true, and it sounds feasible, the DA needs to press charges against him immediately for murder.
Anyone who is a lawful gun owner knows the four rules of gun safety:
1. All guns are loaded. Treat them as such.
2. Never point a gun at someone unless you plan to kill them.
3. Never keep your finger on the trigger until you are ready to shoot and kill.
4. Know your target and what is beyond it.
If everyone applied these rules to gun handling, which are basic common sense, there would never be incidents.
I am sad that a woman lost her life so senselessly to such an arrogant jackass. Did not have to happen.
Hollywood protects its own.
