The last time there was as high profile of a case of a person on Hollywood being killed on set by accident via firearm was 30 years ago with Brandon Lee. It's "only become the individual responsibility" recently because for the better half of three decades the topic wasn't being discussed, because there hadn't been a incident to spark discussion. It's a work place H&S issue. If he had stabbed someone with what he thought was a rubber knife, it'd still be his fault.

Also charges against him were only dropped without prejudice as the prosecutor felt they hadn't gathered sufficient information to bring him to trial. As of April they're still collecting information to possibly return to the charges.
