"There is no easy answer for this, only a difficult one: yes, I would have an obligation to do what's right when it comes to patient care and safety, even if that means making an enemy if a disposition were resented by a colleague. If it were a close personal friend being targeted by the investigation, I would ask to recuse myself, but I would be prepared for that not to be granted. The only thing I would want is to not be the only one making a judgement--having more than one investigator, I feel, is necessary to take politics out of such an inquiry and give it additional objective credibility."
