^ First of all, I don't think the Vegas illustration works. Starfleet was open to the colony of the dangers on the frontier. Just because they didn't tell of the Shedai, which they didn't fully understand at that point, they were brutally honest about the dangers from the tholians and Klingons which should have been enough to convince a sensible person.
As to Starfleet invading the Omari Ekon and torturing the Shedai, I agree, those actions were flat out wrong. i defiinetly didn't support the admiralty in those actions. A lot of innocent people paid for those decisions while the people who authorized them got to grow old and die in their beds. No doubt that is part of the reason why Starfleet buried the records, to cover up their sins.
