Fatigue
The report on Captain Shah by The Daily Mail may be a hatchet job, but it does suggest that he spent all day Friday awake and engrossed in this big trial. It claims he left the court at 9pm straight for the airport to fly overnight to Beijing. Surely he's likely to be tired, and this could lead to poor judgement, possible mistakes and short-temperedness, and not the masterminding of a multinational heist or terrorist plot?
