On the mistrial, maybe, I think that would come down to what all was known about the weapon before it broke, and chain of custody, and a ton of stuff. Probably there’d be a whole investigation of the investigation of the gun.

As far as culpability, my gut reaction is to agree 100% with you. But I don’t know all the details, and I’m not sure why a prosecutor would press charges if its so clearly not Baldwin’s fault. Maybe there’s some legal/financial/political benefit of putting it before a grand jury.
