Ulterior Motives

I received a phone call today that makes me wonder whats the motive behind the call. You see, I had investigated an incident a few months back, and since I couldn't find anything conclusive I have issued a report with possible causes and not pinpointing into one. The reason being is that I can't say with full conviction that I have found the root cause of the incident. So when the call came in, the caller was basically saying that my report was akin to "paralysis by too much analysis" and wanted me to at least identify one root cause that would indemnify a vendor.

What happened was that the caller is the head of another department who have slapped a vendor on the wrist and would like to use my report as means of further punishment. Hence he kept pushing me to select at least a reason so that my report could have been used against the vendor. I felt that they had an ulterior motive as dishing out punitive reports wasn't in my scope of work. They wanted to impose a sort of punishment but wanted to be seen as it was not by them.

Macam mana ni? Baling batu sembunyi tangan? I personally won't do up a report that I have no strong conviction in it. I have to talk it out with my immediate supervisor about this and see what he's going to say. I really hate the feeling that I'm being a pawn in someone else's chess game.
