The only 'opinion' that has any relevancy is what the Police would and wouldn't take action against, which you've just made up and has no factual basis.

As I've demonstrated several times, your opinion on whether McClean used self-defence in the incident at our game is irrelevant because of the series of events (and charges) that followed it.

That also has given you no factual basis to believe he didn't use self-defence when approached by Cardiff fans.

Opinions are irrelevant when facts exist that disprove them.
