If Section 31 is so "official" and not rogue, why in Inter Arma Enim Silent Leges does Ross insist of taking off the comm badges and talking S31 talk to Bashir "off the record"? That's a long way down from Tyler gleefully sporting and using his S31 comm badge. So Admiral Ross and other high ranking people work for Section 31. Does that mean that Section 31 officially works for the Federation? If that were evidence, then the Khitomer conspiracy must also have been officially affiliated with the Federation since Admiral Cartwright and his buddies were involved! I missed that line about Sloan, but all I'll concede is that he is saying contradictory things. (It happens in Star Trek). So there's leeway for both interpretations, but honestly when a Star Trek writer and showrunner outright says S31 is unofficial in the 24th century and he's working on an entire prequel series detailing it, I know which interpretation I'm siding with.
