Now children....
These accidents happen. Stuntmen are killed on set all the time, and Vic Morrow was decapitated, and Brandon Lee was shot and killed on set. Unless someone purposely messed with the gun and intentionally loaded a real bullet, this Rust incident will probably get treated pretty much as the incident on the set of Twilight Zone: The Movie. Charges filed, court hearing, but in the end ruled an accident. Accidents happen on movie sets, space shuttles explode, airplanes crash, police shoot innocent bystanders, Twin Towers collapsed with rescuers still inside, and a kid can die from E coli tainted Jack-In-The-Box hamburger. All tragic events, but still we feel that someone must be to blame or must pay. The bottom line, shit happens. This Rust incident was a tragic mistake, not a cold blooded murder. If this case were an intentional murder, then they will figure it out.
