I was struck by the difference in the interpretation of the term, 'inconclusive'. It was used in the letters to the FA from the professor in charge of the labs which processed the tests.
He said that his expectation after he wrote this in a report was that more tests would be carried out on the player concerned for him to come to a definite conclusion. However, it seems that the FA read 'inconclusive' as 'That's all right then, nothing happening here, move on,' and didn't follow up at all.
It couldn't really be that daft, could it? Players getting away with it because of a misinterpretation of a word?
