'we don't lie to each other or to the customer'. ...
...This sometimes meant that reporting seemed vague and unhelpful when customers didn't know or appreciate the difference between 'probably' and 'possibly' and didn't get that a Comment was just that - a comment, not a statement of fact.
Indeed, and at times in Northern Ireland, particularly when the source of information was such that direct passage could compromise it, it could become morally stressful. The 'form of words' became a particular skill for liaison types like me who had to pass,
and justify, sensitive information between organisations who were all highly sensitive to the idea that they were being conned/lied to/competed with by allied organisations. Usually, not-the-whole-truth sufficed, however sometimes, a black lie had to do, but knowing the history of the information helped to dull the pain.
On one occasion, and given Very Strict instruction that the plan to attack members of X Xxxx at a certain bar was
not to be passed to them, but knowing that the off-duty toms were probably on their way there, and that due to the vagueness of the report there was a high probability of the attack succeeding, and a few other factors, my oppo said something like; 'f this, I'm going to tell them to stay clear', rather than passing through HQNI - Bde - Bn. He did just that, and may have saved many lives that night, without compromising the source, but certainly endangering his career.
Many years later, in a Middle Eastern city, I told this to the Bn's former AIO (he'd been at the bar that night), who wondered why my oppo hadn't been officially recognised for his action; the answer was simple, of course.
'Comment' was frequently a get-out clause, for a multiplicity of reasons. Usually it's a precis, of a summary, and opinion, and prejudice, of previous experience in the particular subject discussed, and shouldn't influence the receiver at all; but it's intended to by the commenter. 'Form of words' is key.
