Currently, there is no rule of evidence, or very little. I think there should be tighter controls. The Judge Advocate General put together a very clear directive of sorts as part of the last reform. But perhaps it should be incorporated into the QR&Os. That way, things would have to be done in a specific order and the procedure would have to be followed. It would require more detail. Obviously, those people are not lawyers, but people who have been assigned to operations, and usually they hold commander or deputy commander positions.
It is also important not to make the system so cumbersome that it turns into a court martial. But, so as not to overburden our commanders, a review system through court martial would probably be a good idea.
