//That may well be the case, but that does not indicate that any bias was a result of a favouring of one team over the other simply on the basis of ethnicity, and that is what would be needed in order for a charge or racism to stand up.//
Yes and officials are impartial (save for the odd match-fixing scandal).
In many football matches there are often a number of questionable decisions against the same side which can sometimes appear to give the impression of bias but this simply serves to question the integrity of the officials and that is plain wrong.
They do their best to oversee the game often in the face of appalling hostility and errant behaviour.
In this instance, to claim racism is utterly absurd and merely accentuates the immorality of the Cameroon camp.
Harshly though they may have been treated at times, Cameroon must accept that sometimes in football decisions go against you. That does not give them the right to demonstrate the way that they did.
The fact that this was a televised match, on the world stage, where the conduct of the team has been exposed in a poor light, sets a terrible example to young girls keen on pursuing a career in the game.
The authorities have to take a firm stance to prevent this sort of nonsense occuring again.
