Saw an interview with Imran Khan today which I found interesting. He claimed that technically many things that had gone on in the game for years before the 92 uproar at Waqar and Wasim could be seen as ball tampering eg the sun creams, picking the seam etc.
He explained his story where he used a bottle top and accepted that was cheating was a one off. He was trying to explain to Ivo Tennant difference between what everyone was doing and what he felt was crossing the line.
Think the ICC need to revisit and be more concise in what is actually tampering and what is not. Sun creams, dirt, sweets, lifting seam... and I am sure stuff we don't know about.
