I could probably speak to that question. There are groups of specialists in different government departments that collaborate quite often on these types of cases.
The complexity of the cases usually indicates that there's not one sole pocket, so we often share resources within the government departments and/or sometimes with other international agencies, law enforcement agencies, or intelligence agencies.
So I guess the expertise doesn't lie necessarily in one particular spot. We'd have to look at it on a case-by-case basis and reach out to other government departments and/or other federal agencies to help us with these kinds of cases.
