It depends on the goal umpire's initial decision. If the umpire has called it a goal, then finger movement would be sufficient evidence that it was touched. But if the umpire has called it touched, then the only sufficient evidence would be if there was clear space between the ball and the hand.
The AFL rule book and interpretation has way too much 'depends'
So it wouldnt be hard to have a concise, consistent phrase to communicate that in the appropriate situation? E.g
'The footage shows the ball was touched'
'The footage does not show the ball was touched',
Irrespective of the umpires decision?
If the footage is inconclusive in the case of touched
Doesnt the phrase we hear 'the footage does not show the ball was touched' apply?
It either shows something or it doesnt, and if theres some twilight zone, its useless to rely on isnt it?
Remove 'clearly' 'finger movement' 'gap' etc
Further, we at home should either 1. See footage that matches what is being said or 2. Not see any footage at all.
Opaque transparency, which is the adjudicators and us seeing different things, is a truly bizzarre concept
Its like the police construct a case and collect evidence and prosecute a case and secretely show it to a jury,
But show the court reporter different evidence.
What possible logic or motivation could there be to do that?
Id rather virtual goal posts and robots adjudicating entirely than the current *smile* mess
