A question of a similar nature was asked earlier.
The challenge that we have when we're involved in criminal investigations is that there are procedural rules, legal rules, privacy rules and different rules with respect to criminal liability, depending on which process you're in.
When we look at it from a law enforcement perspective, for something that the Auditor General or a parliamentary committee may be able to compel someone to come and speak to, they are protected in doing so in some of those processes. There may be a determination later that the person did not provide that information of their own free will and, therefore, we can't use it.
There are times where that actually creates significant challenges for our investigations. We will learn something but can't use it, and then there are subsequent questions about how we are pursuing certain investigative avenues that are based on a process that's not fair to the accused.
