Booing Evra has nothing to do with a lack of respect for 'the issue'. As I said before, there are countless reasons why Evra was going to be boo'd and none of them were because he's black.
And again as I've said before, why would they unreservedly apologise to Evra if they believe he's lied/exaggerated his story? I know I wouldn't.
Liverpool have condemned racism and all forms of discrimination however racism is in the spotlight because of what's happened and that's enough for some clown to make an idiot of himself.
If Utd issued an unreserved public apology for any Utd fans that sung about Hillsborough today would it stop the possibility of a Utd fan singing about Hillsborough at OT in a couple of weeks? And if Utd don't issue this apology, can I condemn Utd for not doing so, sighting that as the reason why some idiot will sing about Hillsborough in a couple of weeks time?
