I think it's more than that. I know someone that hid in Sector 6 to avoid therapy. The bots didn't so much as bother him. Though he was punished for skipping.
And the Wardens could figure out by process of elimination who was in Sector 6 when the murders occurred. You said it was you and some others right? But obviously not just anyone? I mean I wasn't called in cause I wasn't in there, even if I've got enough of a violent background to potentially be suspect.
The life signs of the wasps were what clued them in to anything though.
I'm not so sure we can be tracked in there. I kind of want to test that theory and see what we can get away with. It's just a matter of how.
