From some of the reporting.....there are some details that the public is not yet aware of yet.
Having to do with disregard for overall safety on the set.
Remember early on it was reported that union crews walked off the set, due to concerns over safety protocol being ignored, or some such.
I mention this because the decision to file charges was probably based on more than just AB firing the gun. It was other things that we are not aware of.
Many are saying, including AB's representative, that he will fight the charges. If so and it indeed goes to court, we will know more when discovery is filed, I guess....
