Damningly of Smith's captaincy, his ban was based on him knowing of the plan but failing to take steps to prevent it.
Further, CA's investigation found that it was Smith who directed "that evidence of attempted tampering be concealed on the field of play" – in other words, Smith told Bancroft to hide the yellow object now known to be sandpaper in his trousers.Smith was also found to have "misled match officials and others regarding Bancroft’s attempts to artificially alter the condition of the ball" and "misleading public comments regarding the nature, extent and participants of the plan"."

So, my interpretation is as follows: he only found out about it after the fact and then attempted to hide any evidence of wrongdoing. These are the official findings though, so to call me naive is rather strange, not to mention obnoxious. Would that mean those from the Telegraph that printed that article, and indeed those that adjudicated Smith's tribunal are also naive? I don't deny I'm passionate about this situation, but the only one taking this personally, going by your tone, is you.
