Since you brought it up, yes it is interesting.
- the other people in the car chose to be in the car with him
- they were at the concert with him in Noosa, and they knew he was drunk. they were drunk too , they designated him as their driver.
- if they deemed his driving to be inappropriate, they could have made him pull over and exit the vehicle.
So do you see the parallel? Actions and responsibility - had they crashed the passengers would have born a large percentage of responsibility for electing to be driven by a drunk person.
Similar actions here - refusal to leave when ordered to do so is an abrogation of responsibility. Seriously assaulting someone in their home with a heavy metal object is an abrogation of responsibility. And so on.
So you made good point. Thank you.
