It's a bit of a stretch for me. You might find that if the scousers are still shouting loudly enough (an almost certainty) there might be prison sentences for the cover up, as it's a cheap vote winner. I just can't see it for Duckenfield.I think Duckenfield will have a very hard time given his testimony, showing that he failed to foresee what could happen in the event of failing crowd control. You have crowd control because you envisage what can happen if you don't so that would be to foresee the danger. That is the whole point of crowd control or you would just leave people to get on with it. They had measures ready to be put in place because they could see the danger of not having any in place and that is what ended up happening because proper measures that had been discussed, used in previous years, were not implemented.
Then it is to discuss why they were not implemented. Was it because he was inexperienced? If so, why was the previous years Match commander moved weeks before the event? All very valid questions that should be answered.
I see a fair bit of case law in this regard due to being a member of a few professional bodies for directors and employers and I've yet to see a jail term given out for something like this where someone acted with everyone's safety in mind but just got it wrong. Prison-worthy negligence would have been more like "fudge this, I'm off on holiday. Let the troops on the ground deal with it".
