Note: he was not charged with Insider Trading in this trial. He was charged with destroying evidence. The FCA had already dropped the insider trading charges because they didn't have any evidence. This means that absent whatever they would have found in WhatsApp, they didn't have any evidence that would have corroborated any IMs they might have found, such as any circumstantial evidence of suspicious trades. This article isn't for or against encryption. It simply notes that destruction of evidence cases in the UK tend to be difficult to win because the UK prosecutors apparently are quite bad at it. (Try destroying evidence in the US...very different outcome.)
