Order 66 is in reference to Star Wars, where the clone troopers were with their Jedi leaders and then when they got order 66, they turned on them. I can imagine a scenario where the NG or military assets are in place for "riot control", they tell the targets that they have a credible threat against the target and "we have to get you to safety" and then they load them up and they are gone, off to tribunals and such. Certain people would be the traitors who are being rounded up for trial. USSS is the secret service, arguably the ones who would have eyes on all targets. Anyway, mostly fictional daydreaming :)
