Wow. I got to hand it to you, T'Girl, you rarely disappoint. Regarding the OP: I think your most interesting point is about Section 31. I disagree with you that Starfleet and/or the Federation should actively use them. There are obvious moral implications. Also, relying on such people empowers them, and such people inevitably corrupt the institutions they claim they serve. Sooner or later they would start preying on the Federation itself to protect their own power.
