I’m not a attorney but it would seem that Mr Baldwin should be facing a charge of gross negligence manslaughter. After all, hasn’t he shout to the rooftops how dangerous firearms are?
I am an attorney.
I think it's unlikely he'll be charged with a crime. Criminal law is about intent. The person either has to intend to cause the result or must be acting so recklessly that the result was likely to occur. I believe it will be determined by prosecutors or a grand jury that Baldwin reasonably relied on the assertion that it was a cold gun and thus his actions did not rise to the level of criminality. Don't get me wrong, I despise the guy and would love to see him spend years in jail, but I don't think it's going to happen.
I do think he will be subject to civil liability to the survivors, though. That's a simple negligence standard, which is a much lower standard than criminal negligence. Hopefully, he will be drained of everything he has.
