Guard plays a minor role and is 20% culpable.
The difference is the Guards role was set in contract, he was specifically trained "what not to do", his prime reason for employment in such a job was to give the all clear when safe to do so.
He was the one specifically trained, and aware of the reasons for the regulations HE WAS CONTRACTED TO ENFORCE.
Or do you people that think he wasn't responsible think you can take the proverbial kings shilling, but shirk the responsibility
The mother and girl were responsible in their own ways, but the guard was the only one who broke a specific duty and law.
How was the guard to know the girl was on her last legs and the train was holding her up?
Crystal ball time I suppose..
How is that relevant to his job role.
He has a choice, do the job as entailed, or execute his own judgement.
He chose to execute his own judgement that she would move, his choice, face the consequences.
Or do you not believe in personal responsibility.
