However, Section 31 is not the Federation's only intelligence organization. It is an officially non-existent organization within Starfleet Intelligence.In Star Trek, the Federation employs an organization known as Section 31, but the very existence of this organization is portrayed by the writers as a blemish on the good character of the Federation. One wonders how the writers would expect the Federation to collect vital intelligence data without an intelligence agency, and if they recognize the importance of this agency, one must wonder why it must be condemned to non-sanctioned "shadow agency" status.
Additionally, the aspects of Section 31 that cause disapproval are not even related to its methods of intelligence gathering, but rather on how it acts on the information and the fact that it doesn't answer to anyone.
