A rightful verdict, but sadly this was Football Policing in the 80's, poorly run, little training and poepl like Duckenfield who wasnt up to the task in charge.
Aside from the fact Duckenfiled and those above were incompetent, the FA are complicit in allowing the game to be at a stadium that wasnt up to it, whilst the Government who guide the Police a lot on what they should be doing, were obvioulsy happy to sit back and let Football Policing continue in that fashion without thought for the consequences.
This is more than about one mans ill judged actions, (although his controlling over the whole situation led to such tragic events) there should be thought into why wasnt he properly trained, where was the contingency planning, why wasnt the operation better planned etc, this goes well over and above Duckenfield to both the top echelons of South Yorkshire Police, the FA and the Home Office.
