Shirked, yes; but also passed the buck on to the police who took the brunt of the criticism for the terrible events at Hillsbrough. The ground itself, like Heysel, wasn't fit for purpose and the FA never really took responsibility either.
There's plenty of video on youtube where Liverpool fans brag about getting in to grounds for free by flooding the turnstiles for some to crawl through without paying, even doing so at airports and lying under airplane seats until they get to their destination. There was evidence of them pulling the same stunt in Athens at the stadium where they lost the final to Milan in 2007, so they've never learned or changed their behaviour.
And now they get away with it by shutting down the topic whenever these points are raised.
