Brighter than thousand_suns
I was only 7 when it happened, but those who are a few years older than me remember it very well.Id say football fans all over Europe are well aware of it. In the UK and Ireland, any anniversaries and the recent inquest were headline news, not just sports news. The Sun newspaper blamed the victims back in the day and there are still shops that wont sell that paper, particularly in Liverpool.
I dont find it strange that you, as an American, dont know about it but I would assume that most Europeans here know of it, or at least those of a certain age and/or football fans.
The way the aftermath of the disaster was treated is disgraceful. Not only the coverage from The Sun but the way the police tried to cover up the fact they had a lot of blame.
