It is no secret that over the years the U. S. Government Accountability Office has published numerous reports on private military and security contracting issues. To its credit the GAO goes to great lengths to gather information from all relevant actors in order to write as accurately and thoroughly as possible. All of their reports specify in an appendix the methodology it uses in writing its reports, including the types of people they interview, although they are not listed by name.But what is less known is that GAO makes transcripts of the interviews it conducts. Although the GAO is exempt from complying with the Freedom of Information Act it, admirably, often makes those transcripts available to those who request it.
