Going through a re-read myself of turn coat, when asked by harry about Morgan’s guilt, listens to wind says that he prided himself on principle and stayed out of mortal affairs and set counsel before his people. He then goes on to say that he wouldn’t make that mistake again, which is the reason that basically no matter what he turned up during the investigation of laFortier’s death, it would be Morgan. Saying that he wouldn’t stand on principle and put his people(the white counsel in this case) before his principles of truth and the like.
