Do you really think using a squash ball was illegal?! He simply put it in his glove! The way you are presenting the issue, one would think he loaded it with dynamite, lit the fuse and launched it at a Sri Lankan batsman during an over! I'll bet we don't see an ICC resolution banning squash balls in gloves in the future, indicating that it is a non-issue for Australians or our good friends in the sub-continent.
What is disgraceful and shameful however is that the Australian cricket team refusing to confirm the rumours that Gilly is actually a boundary-hitting robot constructed by the Australian Cricket Academy - don't believe me? - those huge things attached to the side of his head are not ears, they are actually over-sized solar panels to power that thing. Ever wonder why his performance is not as good when the sun goes down..........
