Technically he was never arrested or charged, so the presumption of innocence doesn't apply - that's just a status afforded to anyone accused of something. Innocence outside of a legal framework is different, and I doubt we'll ever know. He's a weird f***er, whatever else he may or may not be.
And yeah, it's a tragic song... if it had been played for years, fair enough (many clubs do that) but forcing that on us all just makes me want to take my seat after kick-off. Maybe a good ploy to sell more beer!
