That's a great and very reasonable question.
We have highly qualified ATIP analysts, many of whom have served as intelligence officers, and so they are very well placed to do a line-by-line analysis of whether any of the exemptions apply. That is reviewed by supervisors to make sure the maximum amount of information has been revealed. That's our default. A very high number of exemptions are applied, primarily as relates to lawful investigations but also as relates to information that would be injurious to national security.
