and spend the rest of the time spinning the "accident" into Baldwin being the victim,
There are plausible arguments to it being a genuine "accident". If a real/loaded gun got improperly put on the gray cart, which is only supposed to have cold guns, when David Halls pulled it off and called it a "cold gun", he may not have actually verified it was a cold gun. He could have just assumed it was because it came off the cold gun cart.
It's clearly negligence on his part. I'm just not quick to assume it was a sabotage.
