First thing I would do if I thought I was being watched would be to just stop all together, I'd imagine that would be most if not everyone's reaction.
Through of this, some of which I probably agree with to some extent, it's all speculation, I would imagine that once the news broke in SA about the ball tampering and then allegations about the ashes followed, every broadcaster would have gone over all the footage of the Aussies in the field through that series with a fine tooth comb, and if I remember correctly, the only thing they found was Bancroft with a packet of sugar in his pocket after a tea break. If it was happening to the extent that everybody believes and if Warner is the simpleton that everyone claims, there would surely be some footage that proves this theory unequivocally.
Anywho, let's hope the SCG has a bit of life in it, hearing word that Finch and Marsh have been dumped for Labuschagne and Handscomb with Labuschagne to bat at 3..Joe Burns and Matt Wade would be hurting a bit right now I'd imagine.
