Safety and the way it’s applied in the real world in any industry is an alibi at best. Like the alibi used by the Sharon Stone character in Basic instinct where she had previously written about a murder that was subsequently committed in exactly the same way.
You’re covered if you make a public song and dance about the details or circumstances of your crime in advance and then it subsequently happens; you maintain a very high level of deniability. Couple that with a distinct lack of prior accidents and you’re pretty much free to claim you have a robust, worlds best practice safety system even if you don’t.
