He should though be pulled/nicked for lying about it all this time though.
The lying (and not just by Duckenfield) is what people should be brought to justice for.
The original mistake, to open the doors or not, is not one I would have wanted to make.
Would people have died if he hadn't opened them? We'll never know. But what we do know is the crush outside the ground was being caused by Liverpool fans operating their well-known tactic of trying to force their way in without paying.
But even after the gates were opened, the ensuing disaster could have been avoided if fans had been directed to the outer pens.
Duckinfield said at the inquiry that he didn't know about previous issues with overcrowding in the central pens and that the previous Senior Officer, who Duckenfield was taking over from, was reluctant to pass on his knowledge. Nor, it seems did any other officers on the day.
Its only a guess but it sound like Duckenfield was probably not very popular with his colleagues who would probably be very happy to see him make a balls of the job.
