It's a bit of an idealistic view unfortunately, it would be like the referee standing on the centre spot and officiating from there.....
Thats what the donkey who refereed the ressies the other night did..
The point is the lino most at fault was surely the one who did see it but did not have the balls to call the ref over and say. "I saw a hand ball", the ref then has to make a decision.
The lino would not make a decision, he must however say what he saw.
The three officials were wrong and I think they have a duty to raise any incident they see, and not hide behind the fact it was not in their half!
If the lino is on the halfway line as he was in this circumstance, of course he could see it, in fact he said he did.
How many times when a fight breaks out does the lino from far away point out that he saw a player kick or strike out when the refs back was turned, the player always gets dissmissed.
