We saw some footage of Baldwin practicing drawing while on set- it was the same set but he was just rehearsing- it wasn't when the people were actually shot.
I saw it on fox. No, I don't have a link.
Anyway, we were observing him and he had his finger on the trigger- if not squeezing it- every time his hand came out from behind his blazer.
I think he maybe was being honest when he said he didn't pull the trigger. Could it be possible that he had the trigger squeezed as he drew, so when he pulled the hammer and released, it fired? I don't know what kind of revolver it was.
It certainly is probable that he's really that ignorant about guns and gun safety.
Regardless, as the actor with the gun in hand and as the head honcho of the whole shitaree, it's his fault entirely. But there will be no real justice.
