I agree with retrospective action when there is clearly no contact, and that should be an immediate suspension. The very grey area comes in where there is contact, as who can say how much contact causes someone to go over. If it can be proven that the attacker instigated the contact then again I'd agree with retrospective action, but it needs to be very clear that this was the case.
It is impossible for referees on the pitch, players are expert at feeling contact and going over whilst they are still teenagers, arguably sometimes before they reach that milestone.
