It would be good if the Inquiry called John Cooke and asked him the specific question -
'Exactly who ordered you to order Sqn Lr Burke to stop assisting the BOI and why?' I know JC and will never believe he would issue this order off his own bat - he has far too much integrity for that.
Then call that individual and so on up the line until we find out exactly who it was who originated the order and for what reason. Their Lordships on the Inquiry are in a prime position to probe this line and clear up the muddied waters.
This is a very significant point in this whole sorry affair.
