We wanted to make sure we dealt with this in a responsible way. The department conducted the internal investigation, which was the appropriate first step. When it ran its course and got to the end of what the department is capable of, sharing the information with law enforcement was an appropriate step, so that they can determine whether a further investigation is warranted and, if so, how it should look.
I don't think it's appropriate for the government to necessarily be doing it in a way that is not independent. To provide documents to an organization that has that independent status is, I think, important so that it can determine the next appropriate steps.
