Well, to take one example, there were five civil servants—government doctors, Tamils—who stayed on during the war in the war zone, and were extraordinarily brave. They probably saved tens of thousands of lives with no thought to their own.
Of those, four were detained at the end of the war and forced to basically renege on everything they'd said during the course of the war. They were put under extraordinary pressure and forced to recant. They had previously talked about war crimes but were then forced to take that back.
I don't think that it's now particularly a category of government employees as opposed to just any civilian or citizen who can't really raise these issues. Certainly it's something that I think is very difficult for people to confront openly in Sri Lanka.
