I think someone advised him not to say "I shot her, it was my fault" because it could mean instant lawsuit and he'd have no recourse to mitigate the damages.
I'm sure an insurance policy is involved... somewhere... no point in giving the insurance company any excuse to void coverage.
He might also be in full denial that this could, in anyway, be his fault.
why do ppl think baldwin will bear any responsibility for this at all and not the prop guy/armorer
How does a prop gun "misfire"?
It's a prop.
