Perhaps the legal justification needs to be abstracted from specific cases. Only if a specific case fulfills the justification can that justification be used in secret prior to full execution of that move which then requires full disclosure in post mortem of the event. A non-indefinite yet reasonable time limit should be another requirement that forces either rescinding the justification and/or requiring full disclosure.

This way a justification can be made without details being made public that would alert a sensitive target. It is also necessary to make sure that a potential authorized kill could not be held open indefinitely and the details released publicly in a timely manner.
