It's obviously for an evidential point of view it could be said that there's a difference in relation to the nature of the evidence that each person would be entitled to be in a position to produce on these issues.  In one sense it may be with the exception of general - let me deal with it this way, in relation to the suggestion of orders, we don't accept that we're at all dealing here with the "I am the private in the Defence Force who is merely a cog in the machine, I do not have any discretion whatsoever, I do not know why I was given these orders".  It's clear from what you have heard that there was, to a greater or lesser degree, participation by all people involved in a particular project on the selection of the target and the modus operandi that would be employed.
