I feel the bunker try to find the minute letter of law ruling whe determining g a decision, not a reasonable / probably approach
Look at last night, I reckon 99% of people using common sense would say that there was probably a touch - and would have lived with the decision.
However, since the bunker - with only a minute or two to decide, couldn't verify with 100% certainty it was touched, decided to go back to original decision.
In summary - they need to use a bit more 'eye test' and less CSI approach.
