They are also talking of retrospective action by viewing the incident after the match has finished.
If that is the case, what will they do when a player has been booked, and possibly sent off, for diving when it later becomes evident that the player was indeed fouled. Do they rescind the card and any punishment that followed - what if a penalty was awarded (foul play in the penalty area), will they change the result? This could turn into an absolute screw up, even if the match is stopped to review the incident as in R.U. then we can look forward to extended match time. Look what happened when they changed the offside laws.
Of course the TV pundits don't help the current situation, not very often that two of them agree.
