The way my firm conducts independent investigations is that there are no limits. The objective is to be at arm's length and free of bias. That means having a mandate that is explicit in its independence from the source organization. We decide which witnesses to interview, what questions to ask and what inferences to draw. We will not take, nor would I ever take, direction from an organization in relation to that sort of mandate.
