The problem with any detailed investigation by Parlaiment or the courts is that it will be very difficult to have a meaningful discussion without revealing our intelligence capabilities and that our our friends. I think the Prime Minister was right to announce these deaths and I hope it will have a corrosive, cancerous effect on ISIL. As was pointed out elsewhere, gone are the days of large ISIL convoys of Utes with black flags flying. That's just too vulnerable.
