Chelsea fans chanted "murderers" for what Liverpool fans did at Heysel to the Juventus fans. Chelsea fans slated by everyone in the media.
Liverpool fans boo the national anthem, haven't seen any sort of condemnation in the media or even on Reddit. Some Liverpool fans have spoken up about it on twitter: https://twitter.com/#!/search/liverpool%20anthem (if you would form an opinion by reading some of the tweets)
What the fuck, world.
(I do not endorse Chelsea fans chanting "murderers" any way in the slightest and I was at Wembley for that Semi-Final match, silent for the full minute, utterly disgraceful and whoever did it should never go to a football match again)
