Maybe some of you may think a little differently if you remember that the engineering manager was previously a supervisor at movieworld, so standing there saying you didnt know you needed to do risk assessments, had no formal process for modifying or documenting repairs or didnt know it was part of your job just doesnt fly. Id be willing to bet money there is paperwork burried within the archives at vrtp that has his name on a bunch of processes doing exactly those things. It's lucky the coroner didnt hand down a reccomendation OIR seek to prosecute individual people because he might have been in a lot of trouble if they went digging for evidence.
Edit: by saying that i mean it potentially shows someone was negligent in their duties and can be legally held accountable.
